Hey there, I'm pretty new to Houdini so I suspect this is probably a simple thing I'm overlooking, but I'm having an issue when I am attempting to use a “VDB Convert” node to convert a volume to a VDB. The input node appears to have a density volume and a temperature volume, however when I set the VDB Convert node to look at the incoming density group (“@name=density”) the VDB node shows that it has a density VDB with zero voxels. Alternatively, setting the VDB Convert node to look at temperature seems to create a temperature VDB as I would expect (I guess?). Just wondering if anyone might be able to give me a hint as to what would cause this behavior.
The DOP configuration which creates the Volume is from a free .otl file I found, so I imagine it's doing something fancy in the volume creation that is over my head. Any help would be appreciated, even if it's just a link to some materials for better understanding volumes.
Thanks so much,
