It does both.  Though you can sculpt in Carrara6 (?Pro) now also. I think you can download the demo version still. It really is worth investigating for those who can not afford any of the other costly paint programmes or Z-Brush.

I think it potentially is better/easier to use (more logical!) for those who only need occasional use than anything around, by far!  A few odd quirks in nomenclature and methods maybe, but these are likely to be upgraded regularly for free it seems.

It seems the designer of the app comes from a Max/Maya background (fortunately not LightWave!)--once he gets the message of more regular, "?universal" approaches/protocols ,well, I think it will be  even more fantastic!
