Hi, I have been creating Custom Hair for a long time but since the last update I'm getting this weird artifacts when using the Human Hair Shader, it doesn't happen with the other shaders, and if I send the Character to Blender, it looks fine. The issue persists if I try to render it.
It's not a problem with the normals, textures or UVs.
Any other ideas?
Thanks!

Hi, if anybody experiences this issue, it's due to the vertex colors. So removing the vertex color information solves the issue, not sure if a CC4 issue or an issue from the export. I hope it helps!
