Tried again with the plugin >>35295 on a new project and this time it worked! Could export poses, clothes, hair and even two characters. Guess there was some problems in the jail environment before? Didn't have anything else in MyLibrary so haven't tested with a different environment.

Rendered this image in Blender, in Daz I used two default poses for the guy and girl and in Blender I rotated him a bit and gave the girl longer nipples just to try it out.

The materials for the eyes were correct this time (better than the collada import) but her eyelashes were just black so I removed them. They looked black (incorrect) in Daz as well so I think something must have been missing or gone wrong when I added the Genesis 8 Female. The guy's eyelashes were correct but he still ended up without them in the render because when I rotated his upper body I forgot to select them, so they ended up behind his head.

Rotating both the body and clothes was easy, just had to make sure to select both the body and clothes bones before rotating. The bones looked way better than when using the collada import, which created some dummy bones that appeared to do nothing.

Quite well done this plugin. Here's a direct link to its instructions:

Basically you first install it in Blender, then you install a plugin in Daz to add a "Export Basic Data" menu option (for a .json info file). Then in Daz you save your .duf project file, then export the .json file in the same folder as .duf (same name before extension). Then you import the .duf file in Blender.
