Default Some Fluids Questions...

I'm messing around with fluids and what I'm trying to do is an animation of the 2 in my scene.. but.. what I need it to do is for one to play half the way, THEN the other one starts... how would I do that??

thanks

What 2 things are you speaking of?

Sorry, not sure what you mean...

If you want to have 2 fluids systems working together (i.e. 2 fluids mixing together) currently, that is not possible with this release of fluids

Maya 5 corrects this I've heard....

If that's not what you were asking, then can you elaborate a bit? Thanks!

well if you go into the visor, and in the fluids examples there is a nuke and a meteor... well I want the meteor to start out the animation and then just when it hits the ground, the nuke goes off...

there is a time node in the nuke's attributes, but that's not it...

Can you just animate the fluid emitters? So that they don't start emitting until you want them to?

Default Controlling Fluids

there are two types of fluid flow...on is dynamic based on some lab theories...i dont think that wil be handleable....cause everthing is based on values from other factors like "Temprature", "Heat"....so i think static grid can help....for controling...the fluids flow.....well i will try to do that and lets see .... !!

I know it's the long way around, but have you thought about animating some low-res geometry to get your animation timing right, then:

1. substitute the meteor with the meteor fluid, and match the low-res animation
2. render JUST the meteor.
3. then render just the nuke.

Then, composite them together later.

Sorry, I know it's the long way around, but untill they allow us to mix fluids, the interaction that you want, you may have to fake a bit...

Default Re: Some Fluids Questions...

I could be wrong but I don't think he wants anything to mix. He just wants to control when the fluid examples start calculating!

Oh, if I understand you right, couldn't you just key the rate's of each emitter, and/or fluid to start and stop when you want them to?

Sorry if I still don't get it...

Here are two ways you could affect when a fluid starts.
1. set the startTime on the fluid
2.(if you want to get all the animated force effects, etc) cache the fluid then break the default time connection to the fluid and keyframe it.
