Is there a way to turn the number of voxels in a vdb into something accessible via vex? Short story long, I'm trying to test to see if an object can be turned into a vdb, and if it produces no voxels. Then use a different technique.

thanks

you can probably use volumeres() [www.sidefx.com] Hscript function

or volumeres() [www.sidefx.com] VEX function

to see if any of the dimensions is 0, in which case the volume primitive has probably no voxels

you can probably also use Bound SOP, if it returns all points at origin, the input has probably no voxels

Thanks Tomas! Great ideas. Bound is probably easiest for what I'm doing,

thanks again.

There's a primintrinsic called activevoxelcount.

Thank you Soothsayer, That's another great option. For anyone looking into this in the future, the vex is, assuming your volume is plugged into the second input:
