Hi everyone,

Is it possible to dilate a velocity vector field? The VDB Reshape SDF node only works on sdf fields.

VDB Activate can expand but it only makes active voxels, I would like to expand the vel field values from the border of the field outward.

You can use first VDB Activate to get the desired siza and then a volume VOP with volumesamplevector for sampling the velocities from the border and extend them how you prefer.The idea is to copy the values from the border of the original velocity field to the new empty voxel. This is also done in DOP network in SOP scalar/vector field, but it's not possible to see how.

Sounds like a good idea! Can you explain how to actually do it in the volume VOP?
