Best way to show liquid changing to gas

[sforsyth]

Clear gas?
My advice would be to start with metaparticles (superspray or something). A bit unstable, but worth it if it works. It gets a decent liquid effect for a start. After that, as you can't animate the change from one particle type to another, you'll have to animate a seperate particle emitter, showing it (use a visibility track if you can't get the timing right and all else fails) only where the metaparticles start fading out. Try putting a smoky effect on these, and use facing as the standard particle type. If you're not looking for something a bit smokey, but instead need to show clear gas, you'l have to come up with some way to either "represent" gas, or you could try something using the Thin Wall refraction material...

Not much, but hope it helps!

sforsyth speaks with much wisdom indeed.

There's another possible approch if you can go the plugin way. Nextlimit (nextlimit.com) has their "RealFlow", a quite good liquid-simulator. It's available from their site as a 30-day trial demo thingie, if you want to test it's magic.

It has a whole big thing about gasses alone, so it sounds like you could take advantage of that (like temperature and conductivity)

Anyways, just a thought.

sforsythe - The gas will be blue in the liquid form and change to red when it gets to the gas state. I may have to do 3 separate particle effects a blue liquid, a gradient metaparticle system that goes from blue to red, and finally a red "smoke" for the gas. I will try that and see what happens....Thanks for the reply.

gaggle - I will download that realflow demo if I can't get the particles to look/work right. Thanks for the tip.

Aw shucks, tak for det gaggle, nu er jeg blevet helt roed i hovedet. :blush:
folical9: another option would be to try one of Peter Watje's plugins. http://www.max3dstuff.com/
He's done a few on particles changing colour over time before, think one was called Particles + or Particle Blend. Can't remember exactly, it's been a long time since I messed around with particles. Anyway, might be worth a look.
