First thing I did was add a plane to act as the ground to see better what it looks like when capturing. Then I added a material to it, changed the base color to black, and removed all the roughness, just because I felt like it. I got this.
I have never seen this before. I have made no changes to world material. In a new scene:
- I changed to Viewport shading
- made the changes to to basecolor & roughness
Seems a little dark, but ok. When you add an actual HDLR file as a background texture, I did not see a way to let the meshes use, but not show it as a skybox like this.
Not a big deal. I almost put this under off topic
