I have a problem with the texture of my metahuman's skin. It's imported in 8K. Does anyone have a suggestion to fix this?
Hello there @Louis-andre!
These type of issues have popped around a few times around the community. From what I could find, it’s usually tied to substrate materials.
As a first test, go to Project Settings > Rendering and check if “Substrate Materials (beta)” is enabled. If so, disable it, restart UE, and allow shaders to fully recompile. If the issue persists, turn it back on, and repeat the process. You can also try clearing the shader cache, via deleting folder “DerivedDataCache” from your project directorty, then allow the project to recompile.
If you have Lumen enabled in your scene, there’s a history of conflicts between it and Metahuman. I would suggest opening the asset, and make sure that Nanite Support is disabled. Alternatively, you ca disable ray tracing, using console command “r.Lumen.HardwareRayTracing 0”, then check if the spots dissapeared.
Finally, to rule out system parameters adjacent to UE, please take the following steps:
- Update your OS to the latest version, and update your video drivers to the Developer version (pick the “Clean Install” option if available)
- Alternate between DX11 and DX12
- Switch between FXAA and TSR
