Hi. I would like to use a lot of mesh roads on my map to make things like guardrails, etc. My question is: how optimized they are? Do they have something like LOD's? Or maybe they disapear when they are invisible or small enough? I wonder, because if they are rendered all the time, it will not be good for performance on my map, and I will have to use models made in blender instead. (although I prefer to create such things directly in the editor) Thanks!
