If I am correctly understanding W_B, I think that's a great idea!

A way to explain it (as I understand it) would be to use a dummy object (a null object, a cube primitive or something else) in DAZ Studio, as an animated placeholder for a moving origin of a force field in VWD during an animated simulation.

This way a user could guide and control the way the force field moves during that animation cycle to obtain a desired (end)effect. You could even think about giving that placeholder an attribute that tells VWD how strong the force field must be at any time during the animation. So changing the size of the cube, or its colour, or the number of vertices during the animation could be a measure of power for the force field in VWD.

Giving that placeholder object a pre-determined name would then tell VWD that it is a 'special' object, so it can be separated from collision- and cloth objects.

All sounds doable enough to me : )

Cheers!
