Cloth Pins Modification

Recommended Posts

Hallo!

I want to somehow delete pins that are holding cloth, but have several issues with this.

In simple example, pins get "ungrouped" by solver, but everything is disconnecting (there should be green balls).

I made very simple example file (that also shows how boolcut is destructive to cloth).

My main problem is from more complex scene:

What I couldn't replicate in simple example, but this is what happens when I try to add sopsolver (same as in example file), that is just removing points from group. Without it - it works fine.

Points are not deleted, reordered, does not change topology.

Last thing is WHY I'm trying to delete those pins:

This is what happens when pins from similar spot are being separated by rigid simulation (rigid bodies hidden). I'm suspecting that it's when one "cloth poly" is attached to two different rigid objects.

It won't tear, it will just stretch.

 

Any ideas?
