OC (object creator) is not very flexible. I recommend using anim8or (
www.anim8or.com ) which allows you to do alot more things. You can use both of course, but I wouldn't spend $$ on OC. (you should be able to find a way around the 20 brush limit anyways) For me, if I ever us OC, it's for the texture mapping, though I recently figured out how to do it in anim8or (it's still kind of weird, and you have to map before you move the points around) For OC, I've have been using it's textures for one of my projects though (I'm hoping to be able to use my own later on, but I currently am not very good at making textures.)
