Write VDB From Maya Fluid

[sabareesh rg]

Hi all,

I tried to export Maya fluids through "OpenVDBFromMayaFluid" and "OpenVDBWrite" Node  , Its not exporting sequences .
I seen a currentTime attribute in OpenVdbFromMayaFluid ,but not in vdb write node.

Here is the workflow i followed


Fluidshape  --> OpenVDBFromMayaFluid.VdbOutput --> OpenVDBWrite.VDBOutput --> OpenVDBVisualize.VDBInput

currentTime is connected to OpenVDBFromMayaFluid.VdbOutput node.

still not creating sequence

Is this workflow is wrong ????

Please somebody show me the right way to do this



Thanks and Regards
Sabareesh RG

Hello Sabareesh,

Having a similar problem and wondered if you figured it out?

Seem there is no Time Attr to allow you to update the frame numbers....

Cheers,

we had to change the source code for both read and writing of VDB files to support a frame replacement syntax, volume.####.vdb and we had to change the AETemplate to expose a 'Frame' attribute which was driven by an expression.

otherwise you need to write your own script which loops over the range, changing the output filename every frame.

Cheers Steven,

Any chance you can share the code to support frame replacement syntax?

Thanks!

I would love to, but unfortunately it is my employer's and not mine to share.

Hehe I understand, cheers!

Any Idea why the OpenVDBWriteAnim node was removed after 2.3?

Cheers!
