Hello, I am trying to create a few draped items of cloth. I have planes in my scene, subdivided, with some verticies in a vertex group called “pins”.
I add a cloth sim to the plane and hit “play” and it all works as expected on the first plane. If I rewind and move the geo, however, it stops simulating and the plane remains completely rigid. To “fix” this I remove the plane from all groups and then re-add it to a new group called “physics”. Sometimes this triggers the sim to work again. Sometimes I have to remove the plane from all groups and NOT re-add it. That might trigger the sim to work. Eventually I manage to get something that I like and so I remove the cloth sim modifier to freeze the geo on that frame.
Then I go on to the next plane and it all starts over again.
The problem is that I am now on my fourth plane and nothing I do can make a cloth sim do anything. Adding and removing it from groups does nothing. Closing and re-opening the scene does nothing. I am stuck (and fairly new to physics in Blender).
Does anyone have any thoughts?
