Particle bind between two groups

[frogspasm]

Oh sure, in that case just filter by group.

For example, assign a Particle Group operator to your cloth ball particles and set simulation group to '1'. Then in your bind operator settings, filter by group '1'. Now that operator will only bind particles to other particles in group '1'.

If I have two events, with the particles from each event set to a different Simulation Group (1 & 2), can I use a Particle Physics Operator to make Sim Group 1 affect Sim Group 2, but not the other way around?
