I've displaced points on a grid to build landscape shapes, I'd like to make them closed volumes for VDB purposes, any tips?

You can use polyloft to create polygons on grouped edges.

Or you can ray the grouped edges onto the original grid and fuse the edges together.

Is this what you're looking for?

You can also use Extrude Volume SOP.

Great tips, both those methods work. I ended up deleting prims with the inverse of the map I'm using to displace points, which gave me caps fitting the base of the landscape, from there VDB tools worked great
