Grouping Particle collisions in a DOPNET

[aracid]

Hey all

maybe im missing something silly in POPS, but in a working example, when adding a collision POP in a working pop network, u can generate a group of particles based on their hitcount etc, this is easy within a collision pop....

however what if i plan on doing the collisions in DOPS, ie have my particles interaction with rbd's, how can I create the group of particles that have been hit ?

ie do the grouping in DOPS

any idea on how to achieve this ?

thanks in advance

hey dude

have you tried using Impacts? using dopnumrecords? not sure if they work with POPs, i know you can see the Impacts, but that's as far as i got to look:)

hey jason

Thanks for the reply, i started doing something like that, and came accross the pstate var.

I managed to do this by using a sop solver and storing the pstate in an arb var,

so basically when the particle collides, u get the pstate ==8 for free (i dunno why i didnt spot that)

and all that is needed is a sop solver to accumulate that value and make sure that once its set, it cant go back to 0.

basically giving u something like a persistent group

see u in dec for a fair share of mojitos

Hey Brian,

I didn't notice the pstate attribute bit too. I'll have to check out my sims and get some grouping action going.

Cheers!

Hey Brian,

Do you mind posting an example hip file? I don't see the pstate attribute changing for particle fluids.

Thanks!

Cheers!
