Attempt to quick fog solution with Octane ...

[enricocerica]

Hi,

Working on a new scene (well an old one deeply revisited), I experimented a way to have a quick rendering solution for fog and all in all, the result comes out not so bad.
Who will guess how I achieved that ?

possibly a massive cube which you have then made almost transparent?

Looks very convincing! Very curious how you achieved this effect

A large cubic volume with a specular SSS shader (not what I'd call quick) so probably a series of semi opaque planes at various depths?

The usual easiest way is to composite with a render made with Z buffer (Depth kernel), but as a border is neatly distinguishable on the front of the house, I would think also that it could be a serie of planes with small alpha.

Mostly thinking about a mesh too as you can see the delimitation of it very clearly.
And I agree with ROUBAL, best is to use the z-depth buffer to do that.

NOt sure about the fog ... BUT I LOVE the three stripey people in the corner... I need a close up of them to make my card crashig woes less angerful. : > ))

Nice!!!

for fog you don't need a massive cube but only a tiny plane in front of the camera with a specular material and scattering node.

very nice result! ...i'm waiting...

NICE! I'd always thought you needed a volume as the scattering medium didn't work without one, but that works a treat!
