Particles will only collide with things that match their own groups. If you set a group on a particle, you must also set that same group on the default ground in the tyFlow PhysX settings.
The particles don't need identical groups, they just need to overlap. For example...a particle with group 1 and 3 set, will collide with a particle with 3 and 5 set, but not with a ground plane set to group 2.
