How to fix Transparency w/ Lashes and Alpha Hair in Blender! Cycles & Eevee!

(This tutorial also helps with adding transparency to Sims 4 Object cc. If needed, I can make a post on that as well.)

This is NOT a Tutorial on how to fix broken/ glitched lashes in the SIMS game!!!

It was brought to my attention that others do not know how to fix this issue in blender, so I've made this post to help out. This tutorial works for BOTH Eevee and Cycles! (This only matters at the end when in the materials tab.)

None of the CC is Mine! Ty to ALL creators!

This is work for all methods of DAE exports.

This is Erecen. They will be our tutorial model today.

As you can see, the Alpha CC hair and lashes are not... working like how we saw them in game. So! We will need to fix this up within our Shading Node Wranglers to correct this.

(If you use a GLASS mesh, make sure you are shade wrangling on the GLASS!)

(This picture is only showing which is the Glass mesh!) Plz ignore this if you are not using Glass mesh export on Ripper.

Lashes/Hair Transparency

First import your sim and wire the texture nodes how you normally would. Stay in Shade Editor/Shading tab.

You will now want to Add a 'Mix Shader' node. Search for it by typing in "Mix Shader". Select and now drop it between your Principle BSDF node and Material Output node.

After this, you will want to Add a Transparent BSDF. I added mine the same way as the Mix Shader and have place it under my Mix Shader node.

With this Transparent BSDF node, you'll want to wire it to the TOP Green Circle of your Mix Shader node. (1 in pic below) This will disconnect your current wiring from Principle BSDF. This is fine since you now want to wire the Principle BSDF node to the BOTTOM Green Circle of your Mix Shader node. (2 in pic below)

Afterwards, you will now need to go to your Base Color node; (Where your sims diffuse lies!) It should be the top left node, unless you have moved it. (3 in pic above) Now take the Alpha dot and drag it all the way to FAC on the same Mix Shader node. From here, we need to go to 'Editor Type'.

After locating Editor Type, you now want to locate the sphere listed as Material.

You now want to find the correct SETTINGS tab. Please note how you render your renderings. If you render in EEVEE, take note of the picture above. Same for CYCLES as taking note in the picture above. This is very important since the SETTINGS options switch between these two areas depending on the Engine.

In Eevee, this should be in the first SETTINGS tab in the materials properties tab.

In Cycles, the SETTINGS you will need is located under the tab listed as Viewport Display. From there, a new drop down will be available called Settings. (This is the correct SETTINGS you want)

Either engine will now have a few modes now visible.

For both Blend Mode and Shadow Mode, change them from Opaque to Alpha Hashed. (It is only required to change Blend Mode to Alpha Hashed for the transparent textures to work. Hashing shadows makes a nice balance of translucency and ambient occlusion.)

And that should be it! Your lashes/Alpha CC hair should be working correctly now!

I hope this helps! If not, please feel free to msg me of any other further know issues. Thank you to @spookyxdoom for bringing this topic up!

I even had my bf try it out without knowing a single thing about Blender and they figured it out just fine with this tutorial.

I already plan on doing other tutorials on how I fix overlapping textures as shown below.
