So this is a very old problem and I think the only issue here is that you cant have the static meshes you are merging into one actor’s UVies overlap each other.
Now I have just over 3000 individual wall pieces that make up a maze and I didn’t see this coming.
… and its hitting me harder than a freight train
I had to overlap some of the wall pieces.
(The merge test I did when I started of course none of the pieces I tested were overlapping so I didn’t see this error pop up) LOL
So now I am scccrrrreeee …… ed.
Now I can go through each wall pieces and just scale them shorter and long on the X and Y that should work, so none of them overlap and they barely just touch each other.
Pretty sure that would solve the problem.
I did group them. But I don’t know if this would really help with performance it looks like an in editor feature only.
Anyone have any ideas?
