Rendering VDB from Houdini

Hello everyone,

I’m not sure if I’m at the right place to post my Cycle rendering issue, however could you check this post what I have done here https://blenderartists.org/t/rendering-vdb-from-houdini-18/1239910?u=iiidfx

If it’s a bug…perhaps that could be interesting for the Cycle development.
If not, maybe someone could tell me what I did wrong.

Thank you in advance.
