Default can i make particles collide with other particles from same emmitter?

i need to make an egg timer, so a container full of small particles, they all need to sit on top of each other so that the container is full up, but they keep falling inside each other.

is there a way to make the particles collide so that they will sit on top of each other and not fall through each other?

Dude

Have a look for "interparticle Collisions" in maya on google, theres a tutorial on it using radial fields assigned to each particle. that should do the trick for ya

cheers

this is gonna sound silly, but why not try scaling down your egg timer so the small particles will fill up the area you want filled?

they dont fill it because they fall inside each other so they all just lie on the bottom.

i need them to sit on top of one another.

cheers anyway

Some sugguestions.

You can try making tons of tuny spheres, making them all hard bodies, and applying the same fields to them as your particles.

or

You can try and learn Maya fluids.

or

You can look into a software like Real Flow. It's a pain in the a$$ to use, but you can get some good results with it.

Good luck.

There is now a better way to do Interparticle Collisions, pouring liquids, etc...
Use nParticles.
Check this tutorial by Duncan Brimsmead, one of the developers of Maya Fluids & the Nucleus system etc.

http://area.autodesk.com/blogs/dunca...ith_nparticles


...otherwise, fluids are the way to go.

Just FYI:
The OLD outdated "pre-fluids" way was to do this:
