Hello - I was wondering if maybe my system has some glitch or something.

It seems I can't convert a Fog vdb to polygons/polygon soup with the vdbconvert node or convert node.

Thought I've done it in the past, but maybe I remember wrong and this has to be converted to a surface first?

To create a mesh set from a fog volume, internally it must first build a level set which requires values on both sides of the interface. Hence, need to increase the “isovalue” to a small value above zero to get a result. make sense?
