Procedural Mesh Component getting extreme performance hit

There seems to be an extreme performance hti when using Proceudral Mesh Component? Is this a known issue?
Only a few of these caused the frame to go up from 10 to 50+

I also notice there are no settings for proceduralmesh component meaning I cannot set it to NOW cast shadow

Hi Frozenfire!
Just wanted to chip in here as well. I’m making procedural buildingblocks for my game and I’m getting some serious performance hits when I use open meshes (as in open polygonplanes instead of closed boxes) It seems to be calculating a whole lot more light-info??

figured it out.

In my case I was simply adding too many components to one object.
