I have a rig consisting of 3 objects and a skeleton. One of the objects is a particle emitter, using a ball object to render the particles. I put the ball in a different layer so I could render the balls emitted as particles, but not the original one. The 3 objects, skeleton and ball object were put into a group and linked into another file, and I created a proxy for the skeleton to animate it. Things are good, but I can't find a way to hide that original ball in the linked file. There is no way to put it in a different layer as it's part of the group. The ball particles render fine, but so does the original ball. Is there a different technique that will accomplish this?
