View Full Version : cloth animation help!

05 May 2006, 11:32 AM

i am trying to make a realistic cloth using simulation in 3ds8. the whole idea is for a piece of cloth to fall over a car. i have used a jpg map to interpolate between 2 materials in cloth object properties -between taffeta and silk. i set cm/unit to 30, step size 0,02 and subsample=1. i want to make a 300 frame anim but it keeps stopping somewhere in the middle.

it gives an error 'dt decreased because cloth over-stretched'. i have used a rectangle with the garment modifier with a density of 0,5 (gives around 11.000 polys). when lowering the density i don't have the same problem but i need the mesh more detailed because then the cloth doesn't cover the details correctly and keeps going through my objects.

i tried changing step size to smaller, increased subsample, changed material damping but still have the same problem. did this happen to anyone else? i would be really greatful if someone could give some advice...

Can you upload your file?

yeah, here is the file...

cm/unit should be more like 3.0, not 30.0.
With your value, the cloth sheet comes to 210x30cm long. That's 210 feet!

well, the cloth should be like 6x4meters. from what i realized it was what i had to do (Set cm/unit to 30)... i'll try reducing it and see what happens but i think the results will be different...
