Quote - Topology/polycound/shape - yes. Rigging - no. Both are WMs, but weightmaps in DS and Poser are different (this is why all problems with Genesis import, I think). And while shapes are same, DS and Poser use different morph injection systems (dufs and pmds). So no, it won't be automatic useablility for both figures. My question is how much trouble would it be.

You know usually rigging refers to the skeleton structure and bones position : from this point of view dawn should have the same rigging in both version.

Weightmapping is the technic used to link the mesh to the bones and should be called "skinning" instead of rigging.

Anyway, poser and DS use the same skinning methods with only minor differences (mostly on the hardcoding of end point and the way the skeleton order is read by the program). They use triax weightmap.

The morph injection is different but it is quite easy to workaround : a content creator can make an morph embeded version of his product, import it in DS and then make the duf and data files in DS.
