in theory, the big fog volume is no more needed if you use the inverted sphere attached to the camera, because all the things behind the sphere will be affected by the fog, unless you don't need to set a specific place for the fog

You are right bepeg. It's even possible to use planes facing to camera to control the fog in depth.

I'm maybe wrong but i always use a very big cube to give an end to the fog because i have the feeling it speed up the rendering a little bit.

I also always use a cube with only one polygon by face and not a sphere (with inverted normals as explained above) because it really speeds up the rendering (not just a feeling in this case ). Like with emiters, less polygons is better.

yea, octane rocks!!!
happy rendering

Here is an alternative:

Look for this:

4DM_Cinema4D_Octane_Lights

It automates the creation of spotlights in C4D and some other things for Octane,... and its free
