Put a per-point attribute on each emitter object (eg self._groupID) In the emit ice tree, use emit location to get the groupID and delete the points if they are not from the object you want to be emitting at that point in time

If you Generate a Sample Set, get the PointPosition from the locations and then create an array out of it you can plug that data into an Add Point node without context issues.

Is there a way to use emit from geometry, and switch between the three pieces of geometry? I guess I could use three emit from geometry compounds and just change the emission individually, but I thought maybe there'd be a way of using a Group Geometry plugged into 1 emit compound or similar and toggle which is the emitter geometry at any one time? I thought generate sample set might work but I'm getting context errors. Any ideas? Thanks Chris
