Hello,
Is anybody has ever worked on a animated cloud dirt simulation ?
I actually work on an off-road car animation and I try to create realistic clouds of dirt behind the wheels. I tried with particle. The result on still image si not bad but animated result doesn’t satisfied me.
I already worked on node but I don’t know how to animate it.

If the questions is just how animate textures in general, you can keyframe node parameters. But to make it look good, hmm. I find controlling volume rendering quite tedious (if there isn’t a suitable sim available). Particles plus fake turbulence via texture animation is probably the best you can do without any external sims.

Can you show me some exemples of animated volume scatter node because I can’t se how to animate it.
Finally I improved the particles cinematic and the result seems to be better. I would be glad to get some advice in order to improve the result of the end of the animation.
There you go.

Not the right texture of course for your case, just to show the principle of animating volume textures.

Okayyy !
My bad. I spoke about animating the texture of a displacement modifier.
I can’t find how to make a vector animating solution in the texture node like you do it for the vector animating in the material node.
By the way, thank you for your feed back ! I’ll try your solution 
In principle you can also animate textures used in modifiers. You just need to set ‘Texture Coordinates’ in the modifier config to ‘Object’, then select an Empty for the object. Animating the transform parameters of the empty will animate the texture, then.
Of course this is more limited than waht you can do with Cycles nodes. You can only move, rotate and scale. I wished for quite some time to have nodes for this also…
No problem because I work with Cycles
I’m not sure to understand but I’ll try. I’ll tell you if I fail…
The issue is, that currently one can use those cool Cycles nodes to build awesome textures only inside material definitions. But if one needs textures for something else (like sims or, well modifiers), you can only choose between the basic, predefined ones which were available in Blender Render. If you need something more complex, you have to either stack a lot of modifiers (for the modifiier case) or use images textures.
Here is a blend with the kind of modifier animation I mentioned:

Wargl ! It’s really intersting. I thought the node editor was the same for the material and modifier textures. Finally, maybe I’ll continue to work with particles…
Was a surprise for me as much for you, when I learned that. It’s a pity, but I believe there is quite a bit work going on in that area. If I didn’t misunderstand, even something like using nodes for the modifiers itself.
