View Full Version : few particle problems
beatoperator 12-19-2001, 06:18 AM well, I have instanced geometry on my particles (some CD's). the problem is that I want that cd's do not touch each other on emission, and I don't know where or how to control this! :( is it possible that I make collision between particles somehow?
the second thing that I don't know is how to make CD's spin slowly as they emit...?
thanx for help ( sorry about bad english :) )

Use collision events to make the particles away from each other at certain time or ėvent. Another thing you can do is create a volume emitter with some distance, you can set this at the emitter's attribute editor and then have some space between your emitted particles , then to make them spin animate your original instance ( the model instanced ).
There are several ways to do this but it depends on what exactly you want to do and so maybe none of this could be the solution.
What is that you want to do?

well, exactly, I want heaps of CD's coming out of one box spinning in random ways... I made particle system, and CD's as separate objects. I add CD's as instanced particles...
if I rotate original CD object, every instanced CD spins the same...
I was a 3dsmax user. In max particle system, there was an option that spins particles as they emit, is there anything similiar here?
(at the moment, particles are my weakest point in Maya :) )
I don't know if you know Mel enough but it would be the simpliest way to do it, less than a minute! I could even write a little expression for you but I don't know the exact details and settings of your scene so it might be usesless.
You can do it like this:
Create a volume emmiter and add just a bit of turbulence, animate your instanced objects as desired and then in the particle shape attribute editor go to the Instancer (Geometry replacement ) section and in the Rotation Option change rotation Type to Particle age and Rotation to Velocity. Then you can set a colition event to make them collide without bouncing by adjusting the geoConector Resilience and Friction. If you don't know how to use Collision events or the Collision command, check the manual and you'll get detailed information on how to use them properly.
Unfortunately, the power of maya's dynamics engine is based on a good knowledge of mel, thing that for most artists is not quite pleasant to play with.
I hope I helped in some way. In my last post I said you could add some emit distance to a volume emitter, that was incorrect, you can do it only with omni, surface and curve emittion types.
Good luck!
