I have a simple flip fluid falling into a bowl then launching off the side that is tipped.

The particles fall from the source object and slide along the bowl and fly out the lowest edge.

What I want to do is create a sphere or box or anything that basically cuts off the gravity once the particles leave the bowl.

I'd assume this is “Mask Field” node and that I would plug it into the gravity input on the right that says “accepts mask field”.

The issue here though is that since it is inside an AutoDopNetwork how do I pass along to the mask field the geometry I want to use to mask the gravity?

I thought it would simply be the SOP Geometry node and just put the SOP path to the sphere or cube I am using to mask the non-gravity area.

But once this is all hooked up the gravity isn't affecting anything. I started the mask geo half on the particles and half off to test.

Any thoughts appreciated.
