Default the galaxy project

1st issue - a stable vortexField


i have a particle swarm of 50.000 with random radii. a a turbulenceField has been applied to create pattern. the initial state is now set to a dense ball-like particle cloud. the emitter was deleted. so, the particle count is a 50k, live forever and no new particles will be created. this is my start scene.


now Iīd like to create some spiral shape to the particles. the problem is: vortexField(Y) blows all particles into universe. so Iīd need some stablizing field or modifiy the vortexField in that way so the particles stay together and only receive a spiraling movement. my goal would be to create spiral arms but the particles donīt step outside my XZ-boundingbox. how would I start..?

any input is much appreciated. hereīs the scene if anyone is interested. itīs maya2008. hope itīs not too big.


... it was, but I hope you get the idea from my description.

I had success with a radialField with negativ value sucking everything now into 000. the tricky part tho was to animate magnitude now from vortexField and RadialField to keep a balanced state between these 2 forces.


but it looks too regular still. Iīll try with another Turbulence field to define some character.

after some tweaking. 100k particles right now. I think it needs some nebular added. updates will continue.

hereīs a picture from early state. working with particles is fun! but I think I have to spend some more time with maya dynamics.

Probably a bit late now but you could try a volume axis field, that has turbulence, vortes and uniform effects and would only effect particles inside its volume.

Exactly, as well as either a drag field, or volume radial to keep the particles inside a given area

Also, mess with attenuation on your radial field to maybe only affect those particles closer to the center.

GREAT JOB!!!!!!!
