I tried the Symbiont ELf in Daz.
Loads ok, loaded with bones showing. (as you said)
If I turn off the bones visibility I can't select body parts, only through the Scene tab.
I normally select the body parts by selecting directly on the model.
But it works.
Some of the joint movement was too much, most was set to 180 to -180 deg.
But it is quite useable and doesn't seem to break or distort.
Renders ok both in Iray and 3delight.
Nice job Thanks!

Thank you JayT for the feedback.

I tried today to make the body-parts selectable in DS , but like I thought it seems
not to be possible . this sort of figure is sort of only working in compatible mode
with a extra line in the DS script else it would not even be possible to use it in
DS.

if you try to load the Poser version , sure then you get to select the bodyparts
but the whole vertex paint that influences attached body-parts get lost on load
that is causing breaks in bending.

Ds Might consider one day to support simple WM as it is even used in there Carrara
Program so it would not even be a big step to do it

The figure is even the way provided in Triax mode and not even that activation
makes the simple WM to get lost . Posibilities for DS would be amazing if
it would support this normal feature. it would also ease up the work-flow of any creator
and be allot more stable.
