I wanted to point out the following three links for fellow newbies (I am one) to Sculptris, they came in VERY handy for me already.
1) a free tool for use with Scuptris for creating AWESOME custom materials for use within Sculptris. The program is called "MaCrea"
2) a little essential trick (undocumented) in Sculptris to get multiple materials to work inside scuptris (very handy to understand):
note: see "reply 10" on the following page for the trick : )
3) another free program to use as an assistance tool in Sculptris and several other programs... this one is called "DAG Foreground Reference Utility"
see the video explanation (link) at the following page post, download link is there too:
Enjoy! : )
