Volume render- deep output?

[docaml]

I am trying to render some clouds with deep data output, but no luck. Nuke reads it as deep but render is empty. Actually, file size is only 100kb.
Is there anything special that has to be checked in render settings or deep volume output is not supported?
Best,
Doca

Is your VolumeGrid Shader Mode set to "Volumetric Geometry", if not change it in rendering tab of the shader.

Ahhh, that's the catch! Thank you!
