Houdini Combine / Flatten VDBs

Added 2018-09-06 19:44:56 +0000 UTC

I came across two situation that urged me to find a way to combine or let's say flatten vdbs so instead of having multiple densities (in case you used a simple merge node) you will end up with only one, and those situations are:

- If you are using the Houdini Cloud Lighting Baker tool I created earlier, so if you have a couple of clouds that you merged and wanna bake the light on to them, only the first one will store the color data.

- Another important use of this technique is when you are exporting VDBs to be used with vray volume grid again only one density will be loaded.

I wrote a slightly more detailed blog about it with some pics that will help you understand it better here...
