Speeding up particle motion

[eebling]

here's my problem...I have particles being controlled by a turbulence field and I like the shape and motion of them, but it takes them 100 frames to reach a nice position. Can I speed up this process so I get the same motion...If I try to increase emission speed or change the turbulence field it doen't move the same....

I may be looking at your problem the wrong way but you can set the initial state to get them there from the start...
There's a guy on this forum who's always sugesting creating another time node, unfortunately I don't know quite how to do that and how to connect it all up. That might work too. Otherwise just start tweaking all the setting with a faster emission.

yea, that's not really what I'm trying to achieve...I want them to not be already in position at the start of the scene, I could just set the initial state after the simulation has been running like what you said but that would have them already emitted . What I have is a curve emitter with a turbulence field generating most of the motion of the particles with a conserve of about .7 to keep them under control. Now that makes there motion look really cool, but it makes them go really slow with the conserve value, but if I change the conserve it doesn't get those nice tight turbulence tendrils...So I want the animation that haapens from say frame 1 to 150 to happen in the range of 1 to 45 or something similar...I dont' know if something like the timeWarp node would do this...since it's a dynamic sim I don't think so, and it' not like baking a rigid body sim where you get curves in that can be scaled to different values...Any help would be apreciated....

Just a simple question, why not render out more than you need then do a time scale when you composite it?

Or make a particle disk cache and connect a cutom time to the sim wich advances faster than normal time.

[eebling]

would that be like using the timeWap node..? I didn't think that would work on a cache, since the timewarp works on keys...? or am I wrong, I've only used a timeWarp node on one project...? And rendering and time scaling would work, but shouldn't there be a way to do this inside maya...I don't want to render any more than I have to if it's not necessary.....

Cool man, Itr worked by connecting a new Time node with a multiplier to speed it up. When I first read your post I read it wrong...How come you can't just break the connection on the particles for current time and put something like " = frame *2;"....?

[joojaa]

You can! Make a expression for the timenodes out time.

[eebling]

ohh, I broke the connection on the particlesShapes current Time and typed the expression in there, didn't work that way, but does if I do it for the outTime of the time Node. Thanks for the help.....
