that was exactly the hypothetical node I was looking for, many thanks Tomas

hey guys,

any pointers on how to approach this, basically I have a vbd with density and vel grids, I have processed the vdb and created a clean mesh, now Im looking to transfer the velocity back onto the surface as an attribute so I can render with vertex motion blur.

I thought it would just be piping the same vdb into slot 2 on convertVDB sop to access the surface properties, but that doesnt seem to funtion as I was hoping.

cheers,
Jeff

hmm, wasn't sure if it was my intense sphere packed geo, so tried in a simpler scene.. same issue, so I'm sure it's just me not hitting a checkbox, or something obvious.. but here is a basic scenefile with the issue if that makes it clearer..

EDIT: rebuilt in FLIP and everything is working as expected, really would love to know what im doing wrong though for future ref..
