Hi, I am working with fume fx in maya and trying to render and open VDB secuence with octane, I wish to make the smoke colored with a gradient, I am trying to connect a octane volume gradient to the absorption ramp of a volume medium, but it make the smoke black and shaped like a brick, does anybody know how can I do that?, how can I make my smoke colored with various colors, thanks, I apriciate your help.

Hi Abeoctane,

Would you please share a sample file with a single FumeFx VDB attached, so we can take a look at the settings?

Cheers

Hi Abeoctane,

Here is quick example scene, Vdb exported from fumeFx demo using Octane Volume gradient in Absorption Ramp and Emission Ramp. Let us know if you have any question.

Please note: the VDBs are baked in a very low grid just to fit the max file size.

Cheers

Hi BK, thank you very much, I will try the scene you created, I think the gradient setup in octane for maya is a bit confusing to me, thanks again.

Hi Abeoctane, Thank you !! Hope you will find the sample useful.

Jim has explained to us that Maya API's native UI gradient is not flexible enough to support Octane data type, however, he is happy to look into it for any possible workaround later when we have a stable refactored version. So, fingers crossed
