No problem.

*I just made a slight edit to my original reply.

To reset or 'sphere project' UV: tab to edit mode on the sphere > press 'A' to make sure all the faces are selected > 'UV' menu (next to 'Face', 'Edge' menus etc.) > choose 'Reset' or 'Sphere Projection'

Thank you so much, Whispermode ...

It's something to do with the UVs.

If you disconnect the Displacement node, it comes back.

...or, put the sphere in Edit mode and reset the UVs - that works, too.

Thank you so much for your time! You're absolutely right!

At the risk of being annoying, could I ask you how to ...

The weird thing is that if I click 'Flow,' with the ...

Oh, hehe, I didn't know what the emission node was good for -- I just copied the setup.

Thank you very much again!!

The main issue with how you have your setup is that you are applying the volume medium to the inflow object (torus). You need to hook up the volume medium onto the domain object (cube).

Oh, thank you so much (for the n'th time)! Great!

Also if you want fire in the volume you need to change the ...

Hi,
I can't figure out how to render smoke (Octane 4, Blender 2.79).

Could someone please tell me the correct Blender Octane node settings?

Thank you in advance!

I get the same error, have no idea why...
