I've found DS-format props' DSF mesh can usually be 'ripped' to portable OBJ format using eg $$ DSF Toolbox, but I've yet to figure how to extract their morphs. Also, textures may prove a pain.

OBJ file-size is usually around 3x that of DSF but, sometimes the mesh conversion goes badly, so OBJ bloats beyond acceptable: YMMV...

Has anyone managed to use DS clothing converted to OBJ format as 'feedstock' for Poser Dynamics ? ..

I seem to have a mental block for both DS & Blender, both having UIs that give me a 'prompt migraine', In theory, DS can export several Poser-compatible formats. In practice, I get migraines...

And please don't start me on FBX versions or rigging varieties lest I cry on my key-board...
