Edit: I have filed a bug report here. It contains a minimal reproduction project.
I've been experimenting with PBR materials in Godot 4.0 beta 1 for the first time today, and something doesn't seem right. I have a dirt material on the ground, but instead of being completely matte, the pillar is reflected in it at low angles.
I have set the dirt material's roughness to 1.0 and metallic is at the default 0.0, so there should be no reflections, right?
Edit: How it looks with Specular = 0.0 and 1.0
How do I achieve a realistic, matte dirt material?
