How to exclude objects from cloth's collision? I have a bed in a room with lots of objects. I'd like to put a sheet over the bed by simulating the sheet as cloth falling over the bed (which has collision enabled).

Problem is, I have many other objects around the bed which has collision enabled.

I tried to hide everything except the bed and the sheet, but the sheet is still affected by the collision of the other objects.

I would prefer not to move the bed out of the way, nor disable collision on the other objects because I need it for other simulations.

Is there a way to specify or exclude objects that the sheet can collide with?
Yes. This is possible with Collision groups.

Make a Group of the objects you want the sheet to collide with. (select objects and press CtrlG)

Set that group in the cloth collision settings for the sheet under Cloth Collision &gt; Collision Group:



Now the sheet object will only collide with the objects in the group Bed.
