Thanks a lot guys, very much appreciated!

Stefan, do you happen to be the same Stefan I advised about importing vertex colors at the ZBrush Central forum? :)

You can read all about my MoI ➔ Zbrush export settings in this discussion:

http://moi3d.com/forum/messages.php?webtag=MOI&msg=8109.1

Additionally, I assign Styles to surfaces in MoI, and import in ZBrush using the option to import Obj materials as polygroups. Then I use those polygroups as ZRemesher guides by activating the KeepGroups option. I'll add this to the other discussion as well.

But I don't know if all the mentioned options are available in ZBrushCore. You'll have to find that out.

Have a great weekend y'all,
