I think it comes with 3. It was a zscript for 2.5
I've never used it, as I have gotten satisfactory results with the standard export from 2.5(remember I Mac so no 3 yet)
I've seen some of the disastrous displacement results from the expensive softwares, and I think thats the reason for the codes. oh and I think it creates normal maps too??? I could be wrong.
I just started a WIP using Hex ZBrush and Carrara
