C'mon.  Everyone here wants a particle gun that shoots out pink ponies and have them pile up like they've got rigor mortis.  :-P

Rigid bodies handle large numbers pretty well, why not just make a bunch and fire them off the end of the hose without bothering with the particles?

That's exactly what I need it to do.  I did think of instanced particles initially, but I'd figure duplicating an object, matching the position and initial velocity would be a much easier problem to solve than converting an instance to an RBD.  I could then cull the geometry when I reset the simulation.  Particle event scripting won't let me duplicate an object based on emission.  It's not part of that elite subset of commands that's shared between pEvent scripts and SCOPs.  It lets me get in one or two objects before it crashes.  Now I'm trying to find another way. 

I'm open to suggestions in either getting around the pEvent scripting aspect, or converting an instance to RBD.  Final output really does need to be RBD since I need to have the interaction between the ones lying there and the ones falling on top of the pile.

Would be nice to be able to shoot 300 instanced particles off and convert them to RBD's right after emission...

Hi List,

Try again now that servers are back up.  First email bounced back. 

Let's say I need to shoot out 3000 pink horses out of a hose,

What strange lives we lead.

 

 

and I need them to land in a pile as they would appear if that were to actually happen in real life, can I do this in XSI? 

[kim aldis]

 

You can get them out of the house easily enough by just squirting particles out the hose and using particle instances. Getting the heap up, will be a bit tougher.  Off the top of my head, animate a patch as a base for the increasing size of pile then use a particle collision event to swap in static horses as the moving ones hit the patch. It'll be fiddly but doable.
