Having some troubles with cloth
I am trying to get a scroll unfurl and roll out over a floor. I have the unfurl down fine, I’m just using a Bend deformer. But for some reason, that seems to disable my floor object. It has a collider tag on it. I tried another plane with a cloth tag on it in the same scene, and it behaved just fine. The problem seems to lie in the deformer tag.
Any thoughts? Or other ways of having something unfurl and bounce off of a floor?

Floor object doesn’t have any ‘real’ geometry (points, ploys, edges and normals) so it can’t be used as a collider but you can place a plane where the floor is (just under the floor or use a compositing tag on the plane and uncheck “Seen by Camera”)

I’m sorry, I should’ve been a bit more clear on that. I am using a plane as the floor, not the “floor object”. That crossed my mind, so I tried a cube just to be on the safe side, and it didn’t work either.

Can’t guess without knowing how it’s set up. Can you post it?

ahh, the Bend and the Cloth both want to do calculations on the points. The results can be nasty. If you were unrolling the cloth horizontally you could turn off the bend once it’s unrolled and let the cloth take over (or turn cloth on at that point) and it would drop. But since you are unrolling vertically and the cloth is meant to hit the floor, you can’t turn off the bend and let the cloth take over because once you turn off the bend the cloth reverts to straight in a single frame and the cloth can’t deal with that.
The only solution I see (someone else may know something better) is to use the bend to roll the cloth, do a Current State to Object to freeze that. Then scale inwards with a soft selection to get the cloth not touching itself in the roll, then apply cloth tags to that with Self Collision turned on and let the cloth engine unroll it. Like this but if you need to have the roll be smooth like if it was being done with a bend deformer it would need something different.

I played with it too and ended up at the same solution as brian.
