Hi guys,
I tried a simple animation with a .vdb file in a volume and there's a cloud animation witch is too quick and not continus... at the end of the sequence, the cloud isn't animated.
I don't understand how work the cloud animation in the .cdb panel.
see files enclosed.
thanks for your explanations
Bertrand

Can you check your vdb. I haven't see problem like that.

Aoktar,
it's a.vdb file from this package.

I'll try to give you the .vdb file for testing tomorrow.

I tried to erase and reload my .vdb cloud file and now it works perfectly. So there was a bug somewhere...
cloud is static and look very nice now.
I tried to use explosion.vdb file and I can only see the smoke and no the fire "part".
How can I "active" it ?
thanks

Hi bertritude,
here is the "fire part" of the explosion.vdb file with a texture emission node and a volume gradient node:

Another question :
is it possible to animate for example the cloud to grow and deform with the sequence ?
thanks
