dForce: Exploding clothes

I'm making an animation where the character is performing 18 hits with arms and legs. I decided to put loose jacket on him, and simulate it using dForce.

dForce parameters:

FPS multiplier: 2

Subframes: 8

Iterations (per subframe): 32

Collision Resolution: Base

Collision mode: Best

Collision iterations: 10

Scene FPS: 60

Jacket parameters: default

 

And what's happening: Character lower his arms - jacket explodes. Character raises his arms - jacket's sleeves sticks to it's sides, and as a result - jacket explodes.

 

Is there ANY way for a normal simulation? How to prevent clothing sticking to itself? How to avoid explosion?

    Are you sure the jacket isn't intersecting with somethign non-dynamic? The sticking does suggest it might be.

    What item are we talking about, perhaps others have it and can give you their feedback, unless of course it's not available elsewhere.

    On the surfaces of the jacket, under simulation, there's a self colide on/off toggle you can try. 9 out of 10 that fixes exploding clothes problems (usually clothes that didn't come with dforce out of the box).
    Downside it that it'll clip something fierce with itself where it comes into contact (mostly a problem for loose clothes or when it's folding over itself like a dress on a sitting character).

    Reducing collision distance can help, and can also stop other issues.

    When dforce explosions happened to me, it was because it was hitting an atmosphere prop that isn't visible unless the viewport was in something other than Texture Shaded or Iray, maybe Hidden Lines or Wireframe. Anyway, once I hid the prop dforce worked as expected.

    I guess the collision iterations are to high! With this high stteings, the dynamic item reacts to hard, when it comes to a collision! That is what i observed and that's why i lower it mostly to 2 or even 1!
