Burger On The Grill

Part 10: Pouring a Drink--Solid Glass

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I made a burger. I will make that burger into a meal with a soda and fries. Last time, we modeled the contour of the iconic Coca Cola glass. Now we will finish off the glass and add the logo.

Solidify

Apply all your modifiers so far. Select the lowest edge loop and add a face to the bottom of the glass. It does not matter that this polygon is an ngon because at this point, we are not going to be subdividing the glass any further.

Select the inside of the glass up to the rim and delete the extra faces. Select the Rim of the glass and invert the selection. Create a Vertex Group from this selection called NotRim. Apply a Solidify Modifier with 0.001m thickness and choose NotRim as the Vertex Group.

Select extra geometry added by the solidify modifier and delete faces. Scale the inside of the glass on the X and Y axes to line up with the rim of the glass. Select and bridge the edge loops.

Check the face orientation and flip any red faces. Select all and merge by distance to eliminate any extra vertices.

We now have a solid glass to work with. Scale the glass down to match real world dimensions.

Add Logo

To create the image for the logo, grab a high resolution PNG with transparency from the internet. I found this image:

Select the logo and fill with white. Set it on a black background. Blur to soften the edges. This greyscale image can be used in Blender as a displacement map.

To add the decal, we will need to create a UV map. Mark seams and unwrap, creating an island around the area you plan to place the logo.

Link the logo image to the UV space. Stretch the logo island to span the entire space on top of the logo. Any other islands can be placed off to the side of the UV map. We do not need them.

To set up the glass material, add a Principled BSDF Shader and set Roughness to 0 and Transmission to 1. Or simply use a Glass Shader instead.

You will also need a Texture Coordinate node, an Image Texture node and a Displacement node. Load your logo into the Image Texture node and connect the sockets as shown in the image below. Adjust the scale of the displacement to your liking.

There you have it, an empty glass!

Follow me to keep watch for the next part! We will be adding some liquid to the glass.

I wanted to start learning Blender, so here's the result of me following the donut tutorial series by BlenderGuru on YouTube!

[carolinkoehn]

My first attempt with blender, following along #blenderguru ´s donut tutorial series!

[kkprocessblog]

Week #1: Donut (Level 1)

The Blender Donut tutorial by Blender Guru is a series that I started during quarantine, but abandoned after I got stuck on the icing. I decided to start my Blender-learning passion project with this series, as he teaches very basic yet important tools. 

The donut and icing were very simple to do. Because donuts are not perfectly torus shaped, we did some grabbing of vertices to create a slightly deformed ring.

I made the icing a bit thicker, because the one above is paper thin :(

This was where I got stuck last time- at creating the realistic icing. I couldn’t figure out how to dribble the icing, but I finally figured it out this time. So, after creating some dripping effects, it was time to sculpt! I’ve used Maya before for basic box modeling but this was my first time actually sculpting in the 3d space. I added an indent around the middle of the donut, just like real ones have. I’m pretty happy with how it turned out! 

After sculpting, I did my first render, and even though the icing looks a bit wonky, I’m happy with how it (slightly) resembles a donut! 

I was going to stop here and do the rest of the tutorials for the next few weeks, but I decided to keep working because Blender is pretty fun- or at least the basics are...

So, the next step is adding materials. This part was pretty easy because I just needed to pick two colors for the bread and icing. 

I used pink for the classic strawberry donut (my favorite) and decreased the roughness to make it a bit reflective. BlenderGuru also made us do something that made the icing absorb the light, because real icing isn’t completely a solid that deflects light. 

After adding materials to the bread, the first level of this tutorial was finished and I was ready to render my simple donut. 

:D level 1 complete, and I’m really happy with how it turned out :) 

Now for the sprinkles: we used a UV sphere, extruded the top half, and flattened the top and bottom to create a sprinkle-like shape.

We used particle properties to add the single sprinkle all over the icing without having to duplicate each one. I made it a bit thicker as well.

To add different colors to the sprinkles, we adjusted some node properties. This reminded me a lot of blueprints in Unreal that I did for MoCap last semester. 

I chose my sprinkle colors, and will pick up where I left off for next week’s output post. Hopefully, I will finish the donut and be ready to animate it for 9/28.

Statement of Intent/Timeplan

SECTION ONE – Your Final Major Project (guide 150 words)

What is the title of your Project? What will you work towards producing and what is your proposed end point? Explain how this relates to your work and ideas from the Pathway Stage and how it extends your knowledge, understanding and creative ability.

As I have explained in my introduction, being in lockdown for so long has admittedly been a struggle, and it’s had a much bigger impact on my creativity and self-motivation than I had anticipated. I came into lockdown thinking art would be a welcome distraction, when it’s turned out to be the complete opposite. I had no interest in doing any of the things I had proposed to do at home, resenting my ideas even before they had properly taken off. For quite a few weeks, I didn’t do much in the way of art.

This was until I decided to download Blender, a free, yet surprisingly high-quality, piece of CAD software. The last time I used any CAD software was back when I completed my GCSEs, where I created virtual models of my product designs. Although I distinctly remember taking to and enjoying the process, it’s an area I haven’t delved further into since. After seeing some examples of artworks made using Blender, I was (for the first time in a long while) eager to give it a go, and thus have begun following a beginners tutorial series on YouTube, with the aim of developing an understanding of the software, meaning I can go on to create 3D illustrations and animations.

I therefore plan to document the progress of my 3D modelling skills throughout this FMP, whilst also developing an idea of how I may utilise the software to create striking visual accompaniments to the music of experimental rock band Mr Bungle. These may come in the form of stand-alone illustrations, posters, short animated gifs, publication advertisements, record covers, or any other area where artwork is needed to promote the band.

SECTION TWO – Influences, Research, Sources and Ideas (guide 150 words)

What are the influences, starting points and contextual references and why are they relevant to your ideas? Indicate the subject areas you intend to research and the likely sources of information including any museums, specific locations, performances, etc you plan to visit. However you should not make extensive lists in this section. Instead you should compile an accurate bibliography correctly acknowledging all references including texts, periodicals, websites and video/DVD’s etc. Enter your bibliography in the APPENDIX.

The initial starting point for this project came out of wanting to learn more in the way of 3D modelling. To do this, I will be using online resources such as www.blenderartists.org, as well as YouTube, where there are some brilliant in depth tutorials, such as the one I am currently working on, a donut modelling tutorial by CGI professional Andrew Price, aka BlenderGuru. This particular series, which is around 5 hours 30 mins long, has been incredibly helpful, introducing me to so many techniques, tools and processes, covering modelling, sculpting, colouring, texturing, lighting, rendering, and even animating. I aim to go more in-depth on some areas of Blender during this project, such as sculpting, depending on which process is most suitable to realise my designs.

As well as using online resources to help me learn Blender, I will also be referencing both 3D artists and poster artists to inspire the concepts and designs for my own illustrations. These may range from illustrators who create 3D graphics, such as Mirko Càmia, to 2D artists working predominantly within the music industry.

I intend for my artworks to be made to accompany music in some form, the band I have chosen being Mr Bungle, an experimental rock/metal outfit fronted by Mike Patton (most well known for his work with Faith No More). I have chosen to use Mr Bungle for a number of reasons, the first being that I am a big fan of their music. Furthermore, the band doesn’t already have a strong visual identity, meaning there is more scope to incorporate my own ideas stylistically. Other reasons, including how the band’s musical style has influenced my ideas, also play a role in my decision to use Mr Bungle, which I will explain in more detail in my blog.

SECTION THREE – Techniques, Processes and Timescale (guide 150 words)

Refer to any techniques and processes you intend to use. Describe the range of media and materials relevant to your project and how you may use them to explore and develop your ideas. Include aspects of studio practice, workshop procedures or the use of particular equipment and software etc. Provide an indicative timescale for your project and indicate the manner in which you intend to divide your time in order to investigate, develop, produce and evaluate your project appropriately. This should be a meaningful plan to you and should be personalised to your project. You may wish to write your plan as a daily or weekly schedule in which case enter your timescale in the APPENDIX.

Most of my work will be completed using Blender, as one of my aims with this project is to develop my 3D modelling skills. However, within Blender, I will also have to use textures from other sources, such as Poliigon (a 3D texture and model website). To develop my initial concepts for illustrations, I will use Adobe Photoshop or Illustrator to create 2D sketches and mock-ups.

Within Blender, I aim to use multiple techniques, including sculpting (for more organic forms), modelling, texturing, as well as composing and lighting. I will also be able to create some small, repeating animations using 3D elements that I have developed.

Although the current Covid-19 situation and lockdown prevent the possibility of me printing physical copies (at least at the moment), I intend to get some of the finished pieces printed for display purposes, such as in my portfolio, even if this is after the FMP deadline. I plan on getting these done professionally at a printers, meaning I can retain the high amount of detail, and correct colouring, in the print form of the artworks.

SECTION FOUR –  Method of Evaluation (guide 50 words)

How will you critically review and analyse your work and determine if it is successful? How will you identify directions for ongoing development? Do you have a method to record the critical response to your ideas? How do you propose to assess the success of your Final Major Project and what will be your methods of evaluation?

My work will be deemed successful if, during the course of the project, I am able to become much more familiar and comfortable with using Blender for 3D modelling. Furthermore, I hope that my outcomes, although retaining their own unique style, will tie into the music and image of Mr Bungle. Due to the circumstances in which this FMP will be created, I may not be able to create a refined final piece, however, the success of the project can be largely judged on the progress of my Blender skills, and how I am able to utilise these to fashion my own outcomes. Even if I cannot create a refined final piece/s, I hope to at least provide evidence of what I plan on doing for ongoing development, both to better my knowledge of 3D techniques, and further explore my ideas in more depth.

Burger On The Grill

Part 9: Pouring a Drink--Cutting Curves

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I made a burger. Now, I will make that burger into a meal with a soda and fries.

Last time, we started modeling the iconic Coca Cola glass and created a simple contour. Now, let's add some indentations.

Cutting Object

To create the cutting objects, I started by adding a Bezier Circle and resizing it to fit the curvature at the top of the indentations. I set the resolution preview to 3 and converted the curve into a mesh.

I separated the bottom half from the top half, moved the bottom half to the bottom of the glass, and then joined the two halves back together. I added edges between the two sets of points and subdivided these edges by 10.

To get the capsule shape from the edge, I deleted the left half of it and used the spin tool.

I resized on the X axis to make it thin. Then, to get the cutting object to match the curvature of the glass, I added a Bezier Curve and adjusted it to match the contour of the portion of the glass my cutting object would be against. I added a Curve Modifier to my cutting object and referenced this Bezier Curve.

Boolean

I set up a Boolean Modifier to subtract the cutting object from the glass and checked the shape of the indentation created. To control the shape of the cutout, I adjusted the shape of the cutting object.

Once I was happy with the shape of the cutout, I added an Array Modifier to the cutting object and finalized the boolean operation.

Clean Up

Because boolean operations leave you with terrible topology and shading issues, I used a ShrinkWrap Modifier to transfer the curvature created by the boolean operation to a new glass with uniform, high subdivision.

To be honest, if you do not mind high polycount and excessive render times, you could stop here with the indentations, but I wanted to try out my hand at retopology, so on we go!

Retopology

To lower the polycount and get proper topology, I isolated a section of the low poly glass before the boolean operation.

Next, I created a guide for my indentations. I added a Bezier Circle and set the resolution to 2 so that it would roughly match the resolution of the glass behind it. I converted the Bezier Circle into a mesh, extended it as before and subdivided the sides by 6.

I planned out the topology on paper first. Then, I added loop cuts and dragged vertices around to obtain proper flow.

Of course, with all that moving about, I had lost the curvature of the indentations, but that was easily retrieved.

I applied an Array Modifier, subdivided by 2 levels and added a ShrinkWrap Modifier targeting the highly subdivided glass from earlier.

Finally! We have good curvature and topology for the indentations. Who knew that one detail would be so complicated?

Here is a overview of our journey so far with the glass:

Part 11: Pouring a Drink--Adding Liquid

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I made a burger. I will make that burger into a meal with a soda and fries. Last time, we finished off our soda glass. Now we will add some coke-colored liquid.

Modeling

How to Make a Beer by BlenderGuru

Select the bottom inside of the glass and Ctrl + to add to selection until the inside of the glass is selected up to where you want the top of the liquid to rest. Shift D to Duplicate, Esc to cancel the Move operation, and P to Separate the selection into its own object.

Select the top edge loop and make a face with F. Inset (I) and drag the size of the new circle in towards the center. Add 20 loop cuts (Ctrl R scroll) around this central circle, trying to make the grid as square as possible near the edge. Poke the central face.

Add 2 loop cuts (Ctrl R scroll) to each of the two outside loops. Select from the central circle up until these subdivided loops. Turn on Proportional Editing (O) and set the Falloff type to Sphere. Move (G) the selection down to create the effect of surface tension.

To get an idea of the scale of that surface tension effect, here are some still images.

To eliminate the strange artifacts that appear between the liquid and glass when rendering, we need to size up the liquid so that it is larger than the inside of the glass and smaller than the outside of the glass.

Set the 3D Cursor to the central point of the top face. Select all the liquid. Size (S) on the Z axis (Z) and drag the liquid a little below the bottom of the inside of the glass.

Next, size (S) on XY axes (Shift Z) and drag the liquid halfway between the inside and outside of the glass, keeping an eye on the bottom sides of the glass.

Since the bottom is a little bulbous, a bit of adjustment is needed. Set the Proportional Editing Falloff type to Smooth. Select the top of the liquid.

Viewing the glass from the side (Num1), size (S) on XY axes (Shift Z) and scroll to expand the range to the point where the liquid is closest to the glass. Drag the top of the liquid halfway between the inside and outside of the glass.

There should now be a smooth taper between the liquid at the top of the glass and at that bulbous point at the bottom.

Check the Face Orientation of the normals for the liquid object and Recalculate Outside.

Select the edge loop at the top of the liquid and Mark Sharp. Then add an Edge Split Modifier and uncheck Angle. Now, the part that we marked sharp will have its normals split, providing a subtle improvement to the appearance of the liquid level line on the glass.

Texturing

Time to add a material to the liquid object!

On the Principled BSDF Shader, set Roughness to 0 and Transmission to 1. Add a Volume Absorption Shader. Set the Density to 60 and the Color to a burnt orange.

So, now you have something that looks a bit like... tea.

Follow me to keep watch for the next part! We will be adding some foam to the top of that liquid.

Burger On The Grill

Part 5: Building a Burger--Melted Cheese

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger. Last time, I grilled up a patty. Now, how about some cheese?

Modeling

Modeling the Cheese by Sanctus – Blender Procedural

Cheese can be draped over the patty with the use of cloth dynamics.

Blender doesn't handle very small simulations particularly well due to floating-point errors, so I have been working on a burger that is sized up by a factor of 50. I will correct the scale to reflect real-world values at the end of the project.

I created a plane and positioned it above the patty. I subdivided that plane a good number of times to provide the necessary detail.

I set the patty as a collision object and added a cloth modifier to the plane. I chose the rubber preset for the cloth modifier. I played the timeline and froze on a frame I liked.

I added a solidify modifier to give the cheese some thickness. Then, I applied the cloth modifier so I would not lose the shape.

It looks pretty good as clay, but I like my burger with some color.

Time for textures!

Texturing

Texturing the Cheese by Default Cube

I started simple with a yellow color for the diffuse, an orange color for the subsurface scattering and numeric values for the subsurface and roughness. Then, I made things complicated by adding noise textures for the subsurface, roughness, transmission and normal.

The subsurface determines how much light enters into the volume of the cheese before it is reflected out.

Roughness determines how shiny the surface is.

Transmission determines how much you can see through the cheese to the meat below; you can see through more in the melty places.

Normal adds more distortion and detail to the surface without altering the geometry.

Here is the textured cheese in Eevee.

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself. But what was similar and interesting?

At the top, you see an image of Yugi eating a burger with his alter ego. This image was illustrated by tmkk9.

As is typical of me, I found inspiration in my favorite anime: YuGiOh.

Part 8: Pouring a Drink--Simple Contour

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I made a burger. Now, I will make that burger into a meal with a soda and fries. Let's start by modeling the iconic Coca Cola glass.

Modeling From Reference

My first step is always to study my reference.

From this image, I could see that I would need 10 indentations in my glass. I created a circle with 10 sides to see how I might add my reference image as a plane facing one of the sides and axes straight on.

Following the reference, I put down vertices to define the contour of the glass.

Then, I used the spin tool to duplicate the edge 360 degrees around the Z axis. I chose to divide the circumference into 40 steps, 4 for each indentation.

I turned on Face Orientation to check my normals and ended up flipping some of them.

Here is our glass so far, a simple contour.

Follow me to keep watch for the next part! I will be fashioning a cutting object to make those complex indentations around the glass.

Part 7: Building a Burger--Frilly Lettuce

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger. Last time, I sliced some tomatoes. Now, let's add the lettuce.

Modeling From Reference: Method 1

I tried two approaches to meshing the lettuce. The first follows the method I used for the orchid.

I added an image as a plane to use as reference. I created a new plane object and positioned it over the reference image, working from top view.

I extruded this plane along the stems of the lettuce, added points and filled planes, following the natural flow of the lettuce in the image.

Once I had this flat geometry, I went to the UV Editor, still in top view, and used Project from View to create the UVs over the lettuce reference.

Modeling From Reference: Method 2

The second method is faster and allows for more detail at the edges.

Modeling Lettuce by Default Cube

In Photoshop, I cropped my reference image and used selection methods to eliminate the white background. I saved the image as a PNG with transparency enabled.

I added this image into Blender as a plane and subdivided the plane by 4 levels. I hooked the Alpha of the image into the Alpha of the Principled BDSF shader so that the transparent parts were hidden.

A couple of settings needed to be adjusted because I was using transparency.

To get rid of clipping in Eevee:

Materials → Viewport Display → Settings → Blender Mod → Alpha Clip

To get rid of black artifacts in Cycles:

Render Properties → Light Paths → Max Bounces → Transparency → 20

I now have a flat leaf of lettuce. But how do I get this leaf to frill?

Displacement

Using Photoshop, I saved a desaturated version of the reference with transparency. This image will be the key to transforming my lettuce.

Back in Blender, I added a Displace Modifier and set the desaturated reference as the controlling texture. I added a Subdivision Surface Modifier with 5 levels so that I could add a second Displace Modifier with the same texture to provide smaller detail. I finished off by adding a Smooth Modifier and increasing the Repeat.

Here is the Lettuce Creation Process:

Positioning

Because I needed this lettuce leaf to fit in my burger, I used Proportional Editing to lift or lower certain points on the mesh until I got something that was less deep.

Fitting the lettuce on the burger was the most tedious part. I duplicated my leaf until I had 3 leaves to rotate and position on top of each other.

In some places the lettuce looked as if it were floating. In other places, the leaves would clip through each other or the tomatoes or the bun.

I wish I knew of a tool that would just smoosh them down together and save me from all the fiddling.

Instead, I placed one leaf down at a time.

I added a Cloth Modifier to the first leaf of lettuce to mitigate the floating issue and added Collision Modifiers to the tomatoes. I checked Self Collisions and increased the Collision Quality to 3.

Dragging the Cloth Modifier just above the Smooth Modifier produced good results. To reduce clipping into the collision objects below, I flipped the normals of each leaf to face upwards.

I applied the modifier stack at a frame I liked, fixed any remaining issues with Proportional Editing, and added a Collision Modifier. Then, I repeated the process on the next leaf.

On the last leaf, I added a Shrinkwrap Modifier to eliminate clipping into the top bun.

And there you have it! The burger is done!

Follow me to keep watch for the next part! I will be making this into a burger meal with a soda and fries.

Part 4: Building a Burger--Perfect Patty

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger. Last time, I formed some shapely buns. But what is a burger without meat?

Modeling

I meshed by first attempt at a burger patty by starting with a cylinder and following reference photos. I ended up with a shape I liked, but the topology was not distributed evenly enough for the Displace modifier I planned to use next.

My next step involved retopology. I started with a torus this time, chose just enough major segments to match my shape and limited the minor segments to 6. I deleted all vertices in the inner loop of the torus and used Grid Fill on the top and bottom to close the inner hole.

The proportional editing tool allowed me to deform the torus to roughly match my first shape. Then, I sized up the torus so that it just contained that first shape, subdivided the whole thing by two, and added a Shrink Wrap modifier to match the outline of the first shape perfectly.

Later, this Shrink Wrap modifier would causing my render to be completely black and empty. Applying the modifier before rendering corrected this issue.

Modeling the Patty by Sanctus – Blender Procedural

My next step involved making the patty lumpy. I subdivided the patty by two again, and then added a Displace modifier with a Cloud texture. Fiddling with the Size of the texture and the Strength of the modifier got me something I liked. Lowering the Midlevel eliminated the strange horizontal distortion around the perimeter of the patty.

Yes, look at that yummy clay! It was really coming along nicely.

But what about texturing?

Texturing

My first attempt used an image texture for everything from diffuse color to bump, but since the image lacked the quality I wanted, I eventually turned to procedural methods.

Texturing the Patty by Sanctus – Blender Procedural

To get the oily effect on the surface of the meat, I played around with two methods. The first was to allow a noise texture to influence the roughness in the Principled shader as in the tutorial by Default Cube.

The second, which I preferred in the end, began by adding a Glossy shader. I set the noise texture to influence the bump of this Glossy shader. A Mix shader was used to combined the Glossy and Principled shaders, and a Layer Weight node plugged into the Fac of the Mix Shader allowed control over the gloss based on which normals were facing the camera.

Here is a screenshot of the burger in Eevee. You can barely see it, but I went to the effort of adding grill lines to the patty.

Adding Grill Lines to the Texture by Default Cube

To sear in the grill lines, I added an Image Texture node, created a new image named "Grill Lines" and selected this node with Node Wrangler to see only its effect on the patty. I marked a seam on the underside of the patty in a circle and unwrapped the UVs. With Texture Paint, I used the Stroke with method Line and held down Alt as I clicked to drag a line across the top of the patty. After doing this to the top and bottom, 5 on each side, I saved the "Grill Lines" image.

A MixRGB node on Add combined the Grill Lines Image Texture with the Noise Texture before feeding the result into the Color Ramp.

See Meat Texture node layout at the top of post.

Part 2: Finding a Reference

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger.

But what kind of burger would I make?

The image at top was obtained from Smashburger. I liked how this burger was constructed with simple ingredients and bright, contrasting colors.

How would I lay out the scene?

What extras would I need to make?

Image with nice composition from SteakNShake.

A burger meal typically includes fries, ketchup and a soda. I liked the warm lighting, the old brick in the background and the way the elements were positioned.

But how would I go about making it?

A burger is similar to a donut as far as the bun is concerned, but those inside elements--the meat, cheese, tomato and lettuce--were a new challenge. How to get those textures--the drape of the cheese, the frill of the lettuce, the greasy lumps of the beef--was a mystery to me. I could also see that arranging the fries by hand would be a tedious nightmare.

There had to be a better way!

Luckily, I was not the only person on the planet to think of modeling a burger, and there is this lovely website called YouTube where you can learn many useful things from others.

I found these tutorials:

Model a Cheeseburger with Procedural Textures by TopChannel1on1

Blender Hamburger by DefaultCube

Since there were features I saw them use that I had not learned yet, such as the use of rigid body animations to place objects like fries and cloth dynamics for placing the melted cheese, I looked up some tutorials specific to these features:

Quick Rigid Body Fun by Blender Guru

How to Make a Blanket by Blender Guru

Armed with some Blender tools, I felt confident that I could conquer this burger meal.

Part 6: Building a Burger--Dewy Tomatoes

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger. Last time, I melted the cheese. Now, let's slice some tomatoes.

Modeling From Reference

Creating Tomato Slices by Default Cube

Here is the Tomato Creation Process.

The first step was to find a nice reference photo of a tomato slice viewed from directly above and add this to my scene as a plane.

I positioned a Bezier Circle over the photo, set the resolution of the curve to something acceptable, and converted it into a mesh. Then, with all points selected, I used Grid Fill and adjusted the span and offset to my liking. I now have the gray, flat likeness of a tomato.

But how do I get the image to stick to it?

UV Mapping and Texturing

I viewed my mesh from the top and used Project From View to get a UV map that matched my reference photo. Then, I created a new material, set the coordinates to be mapped to the UV map, added an image texture node and used the tomato image.

My flat tomato is no longer gray.

Just a note: When using a UV map to apply a preexisting image texture, it is much easier to generate UVs and apply the image before adding further dimension and distortion to the mesh. I learned this lesson from the Orchid.

To make my tomato material more interesting, I used the reference image to add Bump, and, with a ColorRamp, roughness also. I set the subsurface values and color.

Now how do I make my tomato have dimension?

I applied Solidify, Bevel and Subdivision Surface Modifiers. Then, I selected the perimeter of the tomato and created a new material for the rind from a Musgrave texture.

See the TomatoRind Material Nodes image at the top of the post.

I now have a very solid tomato. Time to add some magic dew drops!

Adding Water Droplets

Metalball Water Droplettes Using Geometry Nodes by Weil Labed

Even though Metaballs are a bit finicky and possibly glitchy, they have the unique advantage of automatically merging together when they get close, simulating the real behavior of water.

I created a Metaball and applied the scale. Then, I positioned this Metaball under the table, since I cannot disable render for it without also having the dewdrops on my tomato disappear.

I applied a water material that is a mix between the mirror and transparent shaders.

On the tomato, under Object → Instancing → I had to select Vertex. Then, I had to parent the Metaball to the tomato.

Since the instancing setting affects all the children of the tomato, causing them to disappear in the render, I made sure not to parent the second tomato to the first, but to parent all remaining elements to the cheese.

I set up geometry nodes to instance my dew drop on my tomato. This involved using Weight Paint to specify the area on the tomato that the dew drops would appear.

I have my tomato. Now to place it on the burger!

Positioning

Here is the Tomato Positioning Process.

I scaled the tomato up to the size of the burger and used a Cloth Modifier as I did with the cheese to deform and place the tomato on the burger naturally. I repeated the process with a second tomato, making both the first tomato and the cheese Collision objects.

Look at the burger so far with the different shadings!

Burger On The Grill

Part 3: Building a Burger -- Shapely Buns

After completing the donut tutorial by BlenderGuru, I was challenged to create something similar by myself, so I chose to make a burger.

Modeling

I started with a UV sphere. To get rid of the shading distortion at the center point, I deleted several rings and filled it with a mesh as in the image below.

After using several reference photos to distort the sphere, I had a lumpy bun for my burger.

But what about the sesame seeds?

Adding Seeds

After modeling a single sesame seed from a reference image, there were two approaches I tried to apply seeds to the bun.

The first method used the particle system to distribute points on the bun and instance a seed on each point. This is the method I used for my donut sprinkles. Overlapping is an issue with this method, and there was no easy way to deal with it.

Months after I completed my burger, the second method became a possibility, so I tried again using geometry nodes.

For the extra rotation that allows some seeds to stick out of the bun, see the Random Value node. I have non-zero values for the Max X and Y values as well as for the Z.

Texturing

Texturing was the next challenge. There are two distinct textures on a bun: the crust and the soft inner bread.

How do you go about separating these two textures when they are on the same object?

There are several ways.

The first I tried was to select polygons and assign different materials, but this leaves you with very uniform results, not the best look for an organic object.

The second way was suggested by DefaultCube in this tutorial and basically involves drawing a gradient on the bun to divide the two materials, but with an uneven cut in my very lumpy bun, a horizontal line could not give me the results I wanted.

So I looked into a third way and separated my textures with vertex color paint.

Mixing Materials With Vertex Color by Hola Mundo!

I colored sections in Vertex Paint Mode and added a Vertex Color Node to control the separation of both the shaders and the displacement.

Notice that the Vertex Color node connects to the Fac socket of the Mix Shader to control the separation of the shaders.

Vertex Color also connects to a Value socket of a Multiply Node which then connects to the Scale node socket of the Displacement Node. This Multiply node thus controls the area where the displacement is applied and, by the second value, the scale of that displacement.

For the crust, I applied texture painting to the bun so that the top and bottom had more browning than the middle. A couple of noise textures produced bubbles. A voronoi texture produced cracks. Subsurface scattering softened my bun from hard plastic into an organic material. Another noise texture provided bumps.

See Top Crust Texture and Bottom Crust Texture node layouts at the top of post.

For the bread, I messed around with procedural textures for while and came up with something that resembled vomit... before turning to BlenderGuru once again.

How to Make Realistic Bread by BlenderGuru

I turned a reference image into diffuse, specular and normal maps with the help of Photoshop and the Nvidia NormalMapFilter plugin.

I sampled colors from reference images and used ColorRamp nodes to recolor the grayscale diffuse images and procedural textures. Otherwise, selecting colors, especially for the subsurface scattering, was a lot of trial and error.
