When I combine two PBR materials (with Principled BSDF Shaders) in Eevee through a Mix Shader, the output is pink?
Alone, each Principled Shader works, even if I pass one material through the mix shader, that works. As soon as two go through, it's pink?
I've tried re-creating in a fresh scene with two Principled Shaders, some basic noise textures for color/roughness/normals, but unable to recreate in that case. Seems to be linked to the use of images possibly?
Any help is most appreciated. Thanks!
Have tried the materials on their own, and they work fine:
Top Principled BSDF Shader works fine on it's own:
Bottom Principled BSDF Shader works fine on it's own:
Running a single BSDF Shader through the Mix Shader works as expected
The mask I am using (for context):
