Hey I'm trying to do a little cereal animation however the FLIP which I used from the shelf just goes through the collision, the walls for my bowl which I made into a VDB has thickness, the collision in the DOP is volume as well. Any help appreciate thanks!

Ok so I just re did it and it worked, a different problem I'm getting is if I select the collision mesh outside the DOP it thinks I want that object to be a FLIP???

I just select the flip mesh instead but I'm confused as to why it would switch the FLIP to a different object if I select it.
