I plan on using PBR textures with normal maps and roughness maps. The ones in my screenshots just use a single colour.
I don’t use anything heavy, I get max fps if the meshes are turned off and the code runs. In my original post I tried to do the same thing as you did with the boxes. Make a simple BP with only a mesh and place a hundred objects in the scene. It’s the red gem (first screenshot) one. Still draws hundreds. My light is actually stationary, is that dynamic? It’s the same one you get when you make a new level. I can see in your last screenshot that you are really just using one shelf in a blueptin as a static mesh component and placing it a lot. I’m starting to get my hopes up. Thanks for helping we might find a solution!
