This is getting excessively frustrating. I'm tying to hollow a sphere for use in my map, and every time I hollow it, regardless of how many sides i set it to (usually 8 or 16 depending on size) almost everytime it generates shapes with unusual errors. alt+p will simply delete the shapes, so my sphere will be full of holes.
I've even tried cutting my sphere into 8 pieces, reducing it down to 1 corner and trying to hollow that but even then it creates errors.
Is there a way to make this work, or is it this a bug in hammer?
