Hello, I'm trying to spin randomly a sheet of paper emitted inside a dop and my popspin don't do anything, anyone have an idea of the problem?

I think you need an orient attribute before you can use PopSpin.

Do you know a way to assign that?
Tried with a pop wrangle before the popspin and an attribute create on the paper but it doesn't seems to work
Here's a pic of the tree:

I was a little confused by your network. Not certain why you are making your sheet a pop object when it is more like a Rigid body object. I reconstructed your setup a little bit with a new dopnet and a multiple solver. Note, got the pop spin working pretty quickly without a need for the orient attribute.

Thank you so much!
Yes I wasn't sure if I was going the right way, I'm currently a student and my teachers don't know Houdini enough so I need to search everything myself and the right documentation for a specific situation is really hard to find ^^

I see that the spin seems to work well, I'm gonna try to fit it with the animation and the gravity now, thanks again!
