So I was bored, and I had SDK open. 64 segment, 64 side, and some other random numbers torus. You wouldn't. I would. For my next level design travesty, I carved a sphere of water into a block of water: IT'S SO PRETTY. Expect more soon :3
Carve a torus in a sphere Anyway, I've seen some topic like this on facepunch, where someone carved a sphere into a non-quad displacement in a func_reflective_glass room...
Well, I had a go at repeatedly hollowing a cylinder and I got some interesting results... those pics some the pregressen from about 4 hollowings onwards. Enjoy
