When importing a CC4 character into Blender, unwanted topology-like lines appear on the skin during rendering. These lines persist even after removing the Normal Map and tweaking shading settings.
System Information:
Character Creator 4 Version: v4.51
Blender Version: 4.3
Rendering Engine: Cycles
Graphics Card: RTX 4080
Has anyone else encountered this issue? Any potential fixes or workarounds?

When importing an FBX file in CC4, either through the import button or through u… sing the datalink and clicking on the send avatar button, and using Cycles as the render engine, I get these grid lines, which look very much like the mesh lines. I'm using Blender 4.2.3.
I tried switching between GPU and CPU rendering and it occurs both in the viewport and using the render button. It only happens on skin shaders, all other materials/shaders look fine.
I also tried with Blender 4.0 and 4.3, with Blender 4.0 I get the same issue, in blender 4.3 I get a shader error.

Hi,
I’m having an issue where I can see grid/mesh lines in the Cycles viewport or in the Cycles renders. I don’t have this issue with Eevee and it also only happens with skin shaders, not with any other props or clothes. I’m on Blender 4.2.3 and using the latest version of the auto setup tool. Besides that I have tried both GPU and CPU rendering, which both show the same issue. Blender 4.3 gives me a shader error, but doesn’t have the issue and doesn’t properly show the quality of the skin mat…
Thanks! yep confirmed, Apply a Subdivision Modifier to 2 → This completely fixes the issue
