Although DAZ Studio is a fine piece of software, I find I'm far more productive in Blender for most tasks. The two pieces of software have reached a point where I'm actually able to get a model over to Blender pretty easily. I can set up the materials to work in both Cycles and Blender Internal in just a few minutes. Setting up constraints and IK takes a little longer, but not bad.

But the one thing that's an utter pain is getting a pose from DAZ to Blender.

The only way I've found that works is to export the pose as a .bvh file, then import that. But there seems to be a problem with the bvh exporter that screws up some of the bones (toe, finger, breast seem to be most often affected), and I find I have to actually map from one armature to the other. Any attempt to apply the pose to an existing armature meets with abyssmal failure.

Does anybody have a good workflow for getting pose data over to Blender from DAZ?

There is a plugin that takes stuff over to blender from Daz talked about here.  mcjTeleBlender.  It includes poses...its very simple to use

NOTE:  this takes a posed figure...it does not take a pose from daz and apply it to a figure in blender...if thats your goal, perhaps you can reference his code as a starting point.

Thanks, but I know about mcJTeleBlender. What I'm looking for is a way that brings the pose over to Blender as a pose for an armature, so I can tweak and animate the pose once it's in Blender. I could always just export .OBJ if I just wanted the posed mesh.

Understood, that's why I added the NOTE.
