Hi, I try to understand how to use  VDB occlusion mask node in general.

This node is useful to cutoff or combine target volume (sphere volume) because occlusion comes from camera position and create occlusion behind an object. And as we can see, the occlusion mask VDB data is unique, so I guess to do some operations before applying to  VDB-combine or VDB-clip. 

Thus, if you can explain generic instruction of this node, it would be great, thank you!
