It all started happening when I introduced roughness calculations to my material, and it hasn’t changed even if I remove them.
It goes through shader compilation, but some quads still turn out rendering with the default material as if it hasn’t compiled.
There’s nothing that differentiates these sections from others - it can happen with any combination of layers painted on it.

I’ve tried rebooting editor, editing material, disabling the roughness maps. Nothing seems to work, does anyone know what causes this or how to fix it?
