Hi Robo! I found something weird in CopperCube related to fog and lighting, and I think it might be useful to share.
At first, I thought one of my imported models had a problem with fog — when I walk forward in the game, the ground texture starts turning blue, blending heavily with the fog color. I assumed it was a modeling issue (inverted faces or bad export), but then I realized something important:
The only surface where this doesn't happen is the native Terrain node. Every other surface made from imported models (I'm modeling in SketchUp and exporting as .fbx) shows this blue/foggy effect when I move forward, especially on large flat surfaces like streets or sidewalks.
It seems like CopperCube applies fog or lighting differently depending on whether the surface is a Terrain node or an imported mesh.
Just to clarify — I'm using the custom upgraded CopperCube binary that you released, not the official version. I don't know if this behavior is the same in the original engine, but I thought you'd like to know in case it helps improve the custom build or find a workaround.
Thanks again for all your amazing videos — they've helped me a lot!
