Animated atmosphere volume movement with noise?

[Anonymous]

Hi,

I am currently trying to create an atmosphere volume that has some movement to it, fog movement like you would expect in a sauna for example or from a hot water pool, where the mist gets twirled around a bit and is patchy. I am trying to create this effect with different noise and displacement approaches inside the atmosphere volume, but so far without success. Is this even possible with the atmosphere volume or should I use a normal Arnold volume instead? Did anybody manage to do something similar?

Thanks and best regards!

Hi, I did this a while ago and it rendered very fast, I think I connected a C4d Noise to the atmosphere_volume node Density. But you have to move black and with noise values near the white both or something like that, the best thing is to put a color_correct to the noise and play with the contrast and exposure or gamma.
Also the noise scale will have to be played with to find something that is visible,

Cheers

Hi Diego, thank you very much for your answer! I will try it out this way. I did use a C4D noise, but I just didn't see any difference, probably because of the parameters you described where not set correctly

Is there any way to have this work with fog instead?

I am hoping to get fog in my scene that has noise like rolling mist.

I got it. 

Same principle, just needed to plug c4d noise into distance.

Works really well.

Try it with an Arnold noise. It should look better than fog.
