I haven't used 3ds in a while(HDD failure, and never bothered to get it again), but I recently tried it out and it seems I have forgotten all I've learned :P So I'm starting from scratch, and thought I'd play around with the ink n' paint materials. I'm not completely happy with it, but again, this is just my learning process.
However, I can't see to figure out how to actually make it shade properly.
