VDB Points?

Has anyone used the new VDB Points yet? Have you found any benefit in using it somewhere along your workflow? I'm not really sure what to make of it yet, when/how/if to use it :)

Which node are you particularly on about? ive found VDB advect points, VDB points group and Convert VDB points - i use VDB with points when using a particle sim as pyro for wispy looks or for foam/whitewater in FLIP sims

The new Convert VDB Points SOP will take a bunch of Houdini native points and make a VDB Points grid using it. For H16, there's not really much you can do off the shelf with these primitives other than create, load, save, visualize. It's really there more for studios (eg. dneg :) ) which have in-house tools which know how to operate on them directly before they're useful (practically) I think. They currently display slower than native Houdini points as well unless you set up a visibility group to limit what gets drawn in the viewport.

Ah I see, thanks! So there's no real benefit for us mortals to use? I was thinking like using it to store on disk, for rendering, or something along those lines when you are "done" and don't need to change anything.

if you need to save disk space, you might find it useful to convert large particle sets / point clouds into Points VDB and saving that VDB primitive to disk in your bgeo. Haven't tested rigorously but seems promising.

That sounds interesting :). I'd have to do some tests as well, cheers!
