Thanks, man. Yeah, the free program here called Marbel Clay works strictly with building models face by face like that and that's what I thought Metasequoia's was for, I was just hoping that I could use it to build faces on an already existing primitive that I was in the process of sculpting without having to increase the poly count for the entire model.

Apparently the shareware version (just tried that version out too) has the extra button for allowing four split screens.
