thanks for the workflow on how to creat these texture zones with polygroups. I will admit i dont fully understand polygroups and subtools but that will now be the next tutorials and google youtube videos i will look for so i can understand your workflow you suggested. I understand your concept - just not the technical steps.
As for Blender..... big NOPE !!! I started out 3D modeling for SL using Blender and I can say that I created 3 of my 6 landscape sculpty map packs from within Blender.... but even after 1 year.... I never got comfortable with Blender's horrendous overly geekoid UI. I was convinced by a top SL Sculpty creator from IBM to try Zbrush. And even though i am still learning more about Zbrush with mesh arriving in SL, Zbrush and Sculptris are far easier for me than Blender. I wont go back to Blender unless there is something i really need to do that ONLY blender can do.
As for GoZ.... I almost had it all installed for sculptris and photoshop and then the zaplink function broke in Zbrush. It was working for sculptris but when I tried to get PS to Goz I now get errors when I try to engage it all the time.

I posted the error on the Goz forum but no one responded. So it still sits broken. Didnt know there was a GoZ for Blender.
The error I get is: [FileExecute,gGoZDLLPath,GoZMergeUVs,[StrMerge,subToolPath,appExt]]
thanks again for all the insight!
