Hi dudes,

I’ll try to be short and concise:

Particles and the arrayMapper: I’ve done a simple simulation where particles are emitted by a nurbs circle.
I added a Volume Curve field to make the particles spread on the circle. Then I raised the turbulence value to something low (0.2 more or less).
Everything works fine so far.
But as soon as I try to give particles a color by using the rgpPP color per particles attribute start the troubles.
I attach a ramp by means of an arrayMapper (of course) and when I start the simulation the particles appear in a weird manner and after few seconds disappear, like some kind of “implosion”!!

These issues are not present in Maya 2010 of course. So what am I missing here?

Thank you all very much in advance

Mauro

when u add a rgbPP attribute.the particles’ lifespan will change from ‘live forever’ to ‘constant=1’. the value of ‘1’ is the life of the particle(1 second).u can increase/decrease it as per ur simulation....I dont know what version ur using....but this happens in all versions of Maya.
