Hello,

I have a DOP network with two RBDs (Sphere 1 and Sphere 2), a static terrain and a FLIP fluid tank. These objects all collide with each other in the default setup. What I would like is for Sphere 2 to only collide with the FLIP fluid and ignore everything else. I also want everything else to collide with each other but ignore Sphere 2. I found the collide label and no collide dops but couldn't make sense of how to use them or whether they were the right thing to use. What the best way to go about this?

Thanks.

Check this file ,Of course I know that there is should be better way ,But I don't know it right now !

Thanks Joker. The merge node setups aren't entirely intuitive but your file has pointed me in the right direction.

Quick update.

I found a better way to specify collisions. Saw it on a Peter Quint tutorial: http://vimeo.com/15490394 [vimeo.com] - merge everything together with a merge node set to No Change and use Collide Relationship nodes to spell out the collisions.
