I started up a Blender<->Zbrush guide on Zbrush’s wiki site here:
I figure if there are any other Blender & Zbrush users they can contribute and add to it. And it’s a good resource for those that have any problems importing & exporting between the 2 programs, as that’s mostly what is explained there.
Also the small section on normal maps in Blender requires you to use the Blender build that includes the Tangent space normal maps setting. Which I believe you can download from here: http://www.blender3d.org/forum/viewtopic.php?t=9573&sid=8f50ef3d3ee4ea5bdb705939e2bd914a
It’d be nice if others can add sections on Displacement maps, Cavity maps, or anything else you can think of that uses Zbrush stuff in Blender.
