Hi!
I'm converting an asset to VDB but some geos have no thickness (non-watertight). I remember seing some node/option to deal with those geos. It would give it thickness in a smart way... Know anything about this?

VDB from Polygons: non-watertight geos?

Geo seal by momme is a valid option:

Vdb topology SDF will reconstruct the data, but it will be larger in size.
The trick is to appply a reshape SDF and erode 1-1.5, convert VDB to poly and us negative ISO offset values.
then you can do another VDB from polygons, from a nice watertight piece of geo, this setup of steps will get you
very close to the original source mesh.

In production, we get open surfaces from Modeling often. The common practice is to convert the mesh to an unsigned distance field prior to converting to a signed distance field. ![](/forum/attachment/6546bbad88bee87fd39dfdaa53b2a96de7e0eb55/)
I have an example in the Houdini example file https://www.openvdb.org/download/ [www.openvdb.org] Look for /obj/example_levelset/extruded_sdf
