Need help with dForce collission

Greetings,

With the new dForce stuff, I wanted to try an old v4 Poser dynamics from RuntimeDNA, the Empress Skirt by Witch Didi (now available here at DAZ after the acquisition).  However, I am having problems with the skirt not colliding properly with G3F and am looking for suggestions on how to fix this.  I've gone through several of the dForce threads, including Rob's 'Start Here' thread, but haven't had that eureka moment...

Basic steps taken:

  1. Load in a G3F character
  2. Load the Empress Skirt
  3. Convert skirt from prop to (triax) figure
  4. Parent to G3F -> select V4 as origin (this does a 80% reasonable job of converting to G3F -- it wrecks the tail of the dress, but the hips area is fine)
  5. Simulation -> Add dForce Modifier: Dynamic Surface on the skirt
  6. Set the "waistband" surface's 'Dynamics Strength' to 0 to have the waistband act as an anchor for the rest of the skirt.
  7. Set G3F left thigh bend to -20 and right thigh bend to 20 for a very simple test pose
  8. Added a plane primitive to act as the 'floor'
  9. Run simulation -- it starts from the T-Pose and goes to the posed pose.  But the dress does not collide properly with the legs as the simulation progresses.

I've tried changing from Base to Viewport collision resolution, that just made it take 30x as long for the same results.  I set the mode to 'best', and that didn't help either.  I tried changing the stretchiness setting of the skirt to allow more stretch, and that didn't help either.

Any help here would be much appreciated.

    Are those parts sticking through the dress in the zero pose? You could try posing Genesis 3 Female to fit inside the dress, memorising that pose (Edit>Figure>Memeorise>Memorise Figure Pose), applying your desired pose, and running the simulation.

    In the zero pose, the dress train flies out behind her due to the transfer tool's default projection rigging.  So none of it is intersecting G3F in the zero pose.

    In that case I'm not sure why it would fail like that - have you hidden any parts of the figures (possibly due to needing to remove body handles, cones or the like near the skirt)? Depending on how you did that there is a potential issue - this is now dsicoussed, and noted as fixed in a forthcoming build, in the Start Here thread.

    No, no hidden geometry or any trickery with the geometry editor at all.

    No Anatomical Elements on the base figure either?

    Correct

    Are you using "Base" or "Viewport" for subD? I got rid of that effect by changing to Viewport, then increse the subd in the Parameters tab.

    I have tried both base and viewport, with various subd levels (e.g., both G3F and the skirt at 2, only G3F with subd, only the skirt with subd).  Her legs still go through the skirt in all combinations tested.

    Try running the simulation with either the Node Weight Brush Tool or the Geometry Editor Tool selected. It may not help, but it works for getting dForce to work with figures with geografts attached. Worth a shot.
