Hello! I was trying to build a floor but since I built it in a Octagon form I had to keep copying and flipping my floor pieces, it turned out looking weird with all of the materials glitching through each other and I dont have any solution to make it not clip through each other with having the same shaped floor!
I’d disagree about the poor performance issue, that really doesn’t happen unless your entire build is stacked and clogged with unions, you can also change the collision of unions to give better performance
Although meshes are for the best performance wise, unions themselves aren’t bad either
