Jittery UVs on vdb deformation

Recommended Posts

Hi All,

I'm having a problem here where I'm deforming some terrain geo using a vdb network. These are just like growing particle plants which create little mounds in the dirt as they birth. The terrain UV is jittering around as these seeds move through the vdb, reshaping the terrain.

I've tried a rest position which would normally work. But i've not had experience using the rest with VDB transformation.

I've attached a file and a redshift render. Thanks!

Ok figured out that a redshift tri planar will avoid some UV unwrapping issues I was having. Looks a lot better now.
