'kay I need to get this rendered over-night so some help ASAP would be nice, I've only found tutorials and help the kinda-of help me...

I'm trying to fill a tub with fluid particles, is there a way to make them clump but not stack on top of each other (well I don't mean verticly stack, I want that, I mean I don't want 20 particles in the same spot)?

Inspect -> Par Types -> Your PType -> Interpart. -> Particle Avoidance

Thanks, I tried that before, and I tried it again, but I still can't really get any stacking.
