plazadelmar Posted June 12, 2019 Share Posted June 12, 2019 Does someone know how to crumple cloth into let's say a ball in vellum? Quote Link to comment Share on other sites More sharing options...
kleer001 Posted June 12, 2019 Share Posted June 12, 2019 Start with your cloth on the ground. Create a collision object around in then shrink it until you have the size of ball you want. Quote Link to comment Share on other sites More sharing options...

After some experiments, I think the more natural effect could be achieved by changing rest length to a smaller value and use collider object to create a shape.

Oooh, that sounds clever too! Please post a pic of your results if you can. Quote Link to comment Share on other sites More sharing options...

kleer001 Posted June 19, 2019 Share Posted June 19, 2019 Sweet! I was expecting a crumpled ball of paper, but a shirt is much more exciting. My intuition tells me to animate the rest length down slowly to as small a number as possible, with some non-animated noise or slow noise based on rest position. I might just give it a shot myself.

A combination of animated restlength and your suggestion for collision object to get nice ball shape. 1 Quote Link to comment Share on other sites More sharing options...
Whatsinaname Posted June 21, 2019 Share Posted June 21, 2019 You might also try applicating a force towards the inverse normal direction, using SOP Solver inside DOPs or some POP wrangle. I did that successfully in the old pre- Vellum days to create a crumpling effect. 1 Quote Link to comment Share on other sites More sharing options...
