4 Steps to better VDM with ZBrush

Freelance 3D artist and Vertex panelist Maya Jermy shows you how to master VDM. She will be appearing at Vertex as part of the panel on digital humans.

Vector Displacement Mesh (VDM) is a 3D sculpt used as brush building blocks that enables undercutting when drawing on a model’s surface. But what exactly does it mean?

The simplest way to understand it is to start with alphas. Alpha textures are greyscale images that we often use for sculpting fine-detailed patterns like wrinkles and skin pores. Without them we would have to painstakingly draw the details on by hand, one by one.

Alphas are awesome and quite efficient to use in combination with bushes, but they are basically flat images with black values, and they do not support undercuts and overhangs, which limits what can be done with them.

However, Alpha 3D stores the information of all XYZ axes and does not have any vertical elevation restrictions. By definition, it is 3D as it uses VDM in its system.

All you need to worry about is the polygon density to enable proper projection of the Vector Displacement Mesh onto your model. As I see it, Alpha 3D is an alpha with 3D information, or, a 3D sculpt plastered onto a plane and used as an alpha on steroids.

Step 01 – Sculpt the swirl

To start off, we first need to get a canvas, so head to Lightbox> Project>MISC and select the Brush 3D template. With a clay brush selected, build a little hill in the middle of the canvas, more or less to the size of the swirl. Now, with the radial symmetry on and DamStandard brush selected, start sculpting the grooves and peaks of the swirl shape.  

Step 02 – Fix distorted edges

Make sure to stay away from the edges of the plane. If you accidentally mess up the edges, you have to fix them before saving the VDM: mask the edges, invert mask, go to Tool>Deformation>Relax Plane Grid or Morph to Grid, depending on the level of damage caused to your plane. This should reshape the edges and add more geometry.  

Step 03 – Save out the VDM

To save out your sculpt as a VDM, you need to select a brush that can save all the information contained in your model. With Chisel3D selected, open the Brush palette, select Create and click on Create MultiAlpha Brush. This automatically creates a new Chisel brush out of your model. Your current Alpha texture now contains a VDM of the sculpt with a 3D mark in top-left corner.

  Step 03 – Save out the brush

In order to now save out the brush and create an icon for it, open a 3D sphere and turn it into a polymesh. Divide it a few times and drag out your VDM. Position the sphere to capture the icon, go to the Brush palette, hold down the Alt key and click on SelectIcon. With the icon generated, you can finally save it out with Brush>Save As. Rename your brand-new brush and it is done!

4 Steps to better VDM with ZBrush

Freelance 3D artist and Vertex panelist Maya Jermy shows you how to master VDM. She will be appearing at Vertex as part of the panel on digital humans.

Vector Displacement Mesh (VDM) is a 3D sculpt used as brush building blocks that enables undercutting when drawing on a model’s surface. But what exactly does it mean?

The simplest way to understand it is to start with alphas. Alpha textures are greyscale images that we often use for sculpting fine-detailed patterns like wrinkles and skin pores. Without them we would have to painstakingly draw the details on by hand, one by one.

Alphas are awesome and quite efficient to use in combination with bushes, but they are basically flat images with black values, and they do not support undercuts and overhangs, which limits what can be done with them.

However, Alpha 3D stores the information of all XYZ axes and does not have any vertical elevation restrictions. By definition, it is 3D as it uses VDM in its system.

All you need to worry about is the polygon density to enable proper projection of the Vector Displacement Mesh onto your model. As I see it, Alpha 3D is an alpha with 3D information, or, a 3D sculpt plastered onto a plane and used as an alpha on steroids.

Step 01 – Sculpt the swirl

To start off, we first need to get a canvas, so head to Lightbox> Project>MISC and select the Brush 3D template. With a clay brush selected, build a little hill in the middle of the canvas, more or less to the size of the swirl. Now, with the radial symmetry on and DamStandard brush selected, start sculpting the grooves and peaks of the swirl shape.  

Step 02 – Fix distorted edges

Make sure to stay away from the edges of the plane. If you accidentally mess up the edges, you have to fix them before saving the VDM: mask the edges, invert mask, go to Tool>Deformation>Relax Plane Grid or Morph to Grid, depending on the level of damage caused to your plane. This should reshape the edges and add more geometry.  

Step 03 – Save out the VDM

To save out your sculpt as a VDM, you need to select a brush that can save all the information contained in your model. With Chisel3D selected, open the Brush palette, select Create and click on Create MultiAlpha Brush. This automatically creates a new Chisel brush out of your model. Your current Alpha texture now contains a VDM of the sculpt with a 3D mark in top-left corner.

  Step 03 – Save out the brush

In order to now save out the brush and create an icon for it, open a 3D sphere and turn it into a polymesh. Divide it a few times and drag out your VDM. Position the sphere to capture the icon, go to the Brush palette, hold down the Alt key and click on SelectIcon. With the icon generated, you can finally save it out with Brush>Save As. Rename your brand-new brush and it is done!
