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.

A scene with a concrete pillar and concrete ball in a dirt pit. The concrete pillar is reflected in the dirt.

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?

What happens if you set Specular to 0?

I've updated the post to show the effect of Specular = 0.0 and 1.0. It doesn't seem to impact the strength of SSR. I also linked my github report which contains a reproduction project. I'd really appreciate seeing if the issue exists for others too.
