UPD
Omg. I have similar trouble. But in another direction. I had FULL shading.
The reason for the issue is “DistanceToNearestSurface” node? I was told that there is a possibility that the rendering order, in this case, does not work correctly
But I can’t refuse it or replace it with some other node. Different variations of the “Lighting” settings of the object did not give a satisfactory result.
Maybe someone has encountered such a problem too and knows a possible solution?
@Shanyu, may you ping me please if developers or other experts will prompt a solution
