Hi,

I am trying to expand values in a VDB volume – to expand the active value out from the boundary a few voxels, and fill the new voxels with those on from boundary. I am working with a vector volume (vel).

The Volume Blur SOP can do this on standard houdini volumes, but not VDB.

Does anybody have any suggestions?

thanks,
Chris

Try VDB Smooth SDF or VDB Smooth. Set the operation to Mean Value.

thanks Edward, this seems to be giving me the result I was looking for.
