new toys ! (octane 4)

finally updated Octane to v.4 and my ! there are a lot of new buttons to press & knobs to tweak.
It also feels faster and i wanted to test that volumetric fog thing again.

the test above is still very grainy and took 15 min to render (the character mostly at their lower definition).
i'll try some more & hopefully get some clearer result without eating too much render time - otherwise, well, the story will have to do without it.
