what is this material for? I'm trying to port a model from sfm to blender and after decompiling i found some textures i've never seen before. What are they for and how to apply such textures? Also every texture called &quot;eye-cornea&quot;, so it seems they are related to eyes
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber

So my guess would be that you have found the normal map responsible for creating an apparent bump in the front of the eye.
