Hi guys,

I created a tornado in Houdini and would like to export the vdb files. In the convert to vdb node though, there are no entries in the group selector. Thus I cant select my densitiy channel. When I write “density” manually into the box, it exports empty vdb files.

As I am a beginner, I dont know how to solve this and would appreciate your help. I attached the file

Thank you very much

The problem you were having was the way you brought your smoke back in. You need to use a dop i/o set to import smoke or pyro, and that's how you get your fields. Then you use a convert node, and set to vdb (not a convert vdb).

Hey, I just came back from holydays and read your reply. Thank you so much. I really appreciate it
