POPs to DOPs: RBD Point Object

[few_a_fx]

I've been working on an animation where I have geometry copied onto some particles. The particles are on a attractor node following a curve, and then they collide and pile up. The problem I'm having is the geometry is intersecting each other. I know to stop this I need to make my geometry a RBD. Someone told me I can bring the popnet into DOPs through RBD Point Object node. I haven't had any luck with this, I might be setting it up wrong. Can any give any other suggest or point in the right direction with the RBD point object node.

This is the reference for my animation

reference: cell

Thanks

There is an example in Help called POPwithRBDcollision:

and direct link:

Hope this helps!

Hi,

What you can do is bring the cells into dops at one frame to animate them there and make them collide correctly, not a pop simulation to make the collisions. Your attractor won't do anyting because you won't be using pops. Try the field force in dops instead.

So I'm trying to use this example file to my advantage, but I'm have trouble getting it to work with my popnet. Can this still work, even if my particles are on an attractor, and colliding with geometry? I'm also trying what you suggested miguel, so I'm hoping one of these will work.

So I finally got the cells to clot, by using the "Stack" example in help. However I'm having a difficult time getting my object to rotate on the x axis. I've tried motion dop, adding an expression to the transform sop and to my rbd configured object. Any suggestions?
