I have two Blender files:
Both files use the same rigged model. Both files use the same parameters for their dress simulation as well as their collision object parameters.
Both files contain similar (but not exact) dresses, initially created with the Simply Cloth Pro add-on.
However, their behavior -- when applying a cloth simulation -- could not be any more different. This video demonstrates the problem:
I cannot figure out why the one dress sits normally while the other one expands like a hot air balloon.
Here are the files:
It seems that I got lucky only once with the cloth properly settling. All of the other times I tried (and I've tried a lot, always starting with the same previously-created base file), I get the hot air balloon effect.
Does anyone have any idea what's going on? I've been hammering away at this for a week but with no progress :(
