dForce Simulation: How to avoid exploding skirt while sitting?

EightiesIsEnough

I am wondering, when adding dforce simulation to a skirt while the Genesis 3 female is sitting, how do I make the skirt drape over the seat smoothly without exploding?  The skirt is not knee-length, by the way, but i would like the skirt to drape over the thighs to avoid revealing underwear.

It should be enough to leave some space between the legs and the seat, so that the solver has some free volume to compute the solution. As for draping you may guide it with collision helpers and/or a soft wind.

A soft wind made me giggle 

you would want it to not blow where I was thinking

It may be best to use a play range simulaiton, starting with the chair pulled back and then sliding it into position so that it pushes te skirt ahead of it - and as Padoen says, make sure that the figure doesn't intersect with the chair, trapping fabric between the two.

I'd like to ask, what parameters should I set my simulation settings if I were to use a play range simulation?

Richard Haseltine

You need to set up the animation, then select one of the play range options in Frames to Simulate in the Simulation Settings pane.

Weight paint the sim to not simulate the part she's sitting on?

When I hear wind and exploding skirts!!! I think a bad case of gas and suggest maalox or pepto bismol.hahaha

On a serious note unless you are animating this you could just create a sit down morph for the skirt in blender or hexagon.

If the seat is dense enough on geometry, a dformer could help. Decrease the seat's deform value after simulation to your gusto.

I've mentioned this in other threads relating to dforce animation, but one key factor in "explosions" is the time range occuring in the animation sequence.  For example, if you try to do every type of dforce animation in 30 frames, it's not going to work well because this is only 1 second of time at 30 FPS.  Slow it down by adding more frames over the course of the animation, or add more sub-steps between frames in the simulation settings if you cannot extend the frames.

A more rare issue is the collision offset in the surface settings of the dforce cloth.  Higher make a larger gap between cloth and model which may contribute to initial explosions before the animation even begins, while smaller may cause poke through in later frames.
