Hello. So I was messing around with landscape material and layers, and ran into a problem.
I have 5 layers, using layer blender I have them plugged into base color and everything works fine.
But then I went ahead and added also connections to specular, normal and AO, and now after painting 3rd layer on landscape, it compiles shaders and turns gray. (picture below, black is just unpainted area)
Am I doing something wrong? Please help
Edit: It also gave me this in output log:
LogShaderCompilers:Warning: Failed to compile Material /Game/Materials/Ground/World/Mat_Landscape2.Mat_Landscape2 for platform PCD3D_SM5, Default Material will be used in game.
