So I was experimenting with fog and with some help from a friend on the Facebook Octane group (join it if you're not in it: https://www.facebook.com/groups/OctaneRender/ ) I came up with this. I'm really amazed that Octane can create this wonderful looking fog without even having official support for it yet.

It's really really simple to create once you understand it and since there was a lot of people wishing for a tutorial of it, I made one, added below.

Render time in 1920x710 was about 10 minutes to get it noise free on 3x 980TI and 2x 780ti after I tweaked the render settings a bit. Ain't too bad concidering it's an SSS material.

Have fun!

Octane does support fog, since fog is sort of just a medium scattering with a phase function :) With Octane 3, volumetrics will allow to render fog even more realistically.

Nice render!

Well you're right, but you still can't have the camera inside the fog without having am inverted sphere around it, I wouldn't call that support :-)

perfect Johannes :)

Its every time more as good to think "outside of the box" and see that other people it also do so :)
If you can hack the "box" with simple tricks hack them ! :)
thats the different between the "preset users" v.s. artists as developer.
Thanks for the video :)
