Hello,
I have recently found out about this VDB and it sounds like its an amazing way to work in in Houdini. I haven't really worked very much with Houdini and was wondering if there was any kind of tutorials on this subject? I have already looked through the Siggraph 2013 documents and been to the openVDB website, but I don't think I am fully grasping what this VDB is about. If someone could lead me into the right direction that would be amazing.
Thank you,
Jason Healy

Not that I know of. There's a tutorial on the CloudFX though which makes use of VDBs underneath:

The VDB nodes inside the cloud tools might be instructive.

Thank you, That actually helps a lot on understanding how to setup the network.
Would you be able to help me out on how I would load a .VDB file into Houdini? For example, the examples from the Open VDB website. I loaded them in through the object import, but I am pretty sure that's not the right way for the object loads but there is no network.

To my understanding a .VDB is just the information cached to disk, like you would cache out one frame of, say a Pyro sim, to .bgeo. If you load that in you will only see that information, there is no “network” to see. Or am I missing something?

You can just put in the appropriate path into a File SOP. Or if you're new, the easiest way is to use the main menu, File > Import > Geometry.

Ok, that's what I did. Good to know I was doing it right.
Thank you.

Hello,

if you're still interested, we just added some great stuff on the
OpenVDB website. [
openvdb.org] I created a really thorough HIP file (on the
downloads page [
openvdb.org]), which walks you through a ton of different techniques and workflows. You can check out the
Siggraph slides [
openvdb.org] from our talks as well.
I hope that helps!
