Ncloth Diaper Dilemma

[toonchick]

I am working on an nCloth project in which a cloth object (actually a diaper swallowed by a dog!) passing through some tubular shapes. I animated a poly object along a motion path and used a point to surface constraint to drag the nCloth through the esophagus - stomach etc objects.

I works OK in the larger tubes - but when we hit the small intestines the cloth invariably breaks through the tubes.

Does anyone have any suggestions as nCloth settings which would allow the cloth to pass though the smaller tubes?

Currently i have a cloth thickness of .1 and the self collied width scale of .1. I have a large stretch resistance (200) compressione resistance is 20 bend resistance is .1.

I am pretty confused about the Push Out - Push Out Radius -Crossover Push and Self Crossover Push. Currenly I have them all set to .01 thinking that sould allow the clothe to squeeze through a tight space.

I am really enjoying nCloth and we have had great results with it in various projects so far - but I feel like I am wildly flailing at settings on this one!

Thanks

While it's OK for larger tubes it sounds like a problem which could be solved by adjusting the space scale attribute in the nucleus node. Solver units are meter, so for instance a scale of 0.01 would give you centimeters. Just give your dog the correct measurements.

Otherwise, also try increasing the max collision iterations and substeps as well as checking "trapped check" and "self trapped check" attributes (you never know...)

The problem is likely that the tubes have normals pointing outward, not inward. Thus the pushout and trapped check on the tube object actually tends to push the cloth out of the tube. You could flip the normals on the tubes if you want to use trapped check. Otherwise you could turn off trapped check( on the tubes ) and instead use negative pushout.
