Inside smoke

[Alpa24]

Hello,

I want to make smoke that moves in inside the cylinder continiously for end less frame.
Dont want to emitts from source just there inside the cylinder.

How can i make this ?

Thanking you

To fully understand what you are after, tell me if this is similar to what you are asking
--emit dense smoke into something like a concrete mixing barrel
--then shut off your emitter (similar to realflow)
--then let's say the barrel is on its side at an upward angle and rotating
--then you want the smoke to continously roll and hold a volume

If this is close to what you are after, you would need to make the smoke very dense and keep the gravity up. As far as I know, ffx calculates smoke to behave like real-world smoke that is always going to have some diffusion and expansion.

Thank you for your reply,

Well my audio is A gas jar is filled with hydrogen gas.
So i dont want to emit but just roming inside the gas jar.


Thanking you.

This would be something that wouldnt last forever if you just emit smoke inside of a container and then shut off the smoke density because the nature of smoke is that it tends to diffuse if moving. You might try some techniques such as emitting from particles or a moving object so new smoke is constantly being born and then having the smoke die off before it diffuses too much. You can use ffx noise or wind turbulence to perturb the smoke. The difficulty will be to keep the smoke from appearing it's being born. With some tweaking, I'm sure you can get what you're after.
