Yes it can make perfect tiling textures. And they're yours to sell. Make whatever you want. The Loom is a free merchant resource. You just can't sell the Loom or matmatic, because they are FREE! But whatever you make with them using your own designs is yours to keep and do with as you please. Sell the scripts you make. Sell the tiles. Whatever.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
