Compositing Environment in Fusion Tweet

[slepy8]

Hi guys!

I'm working in C4D plugin.
Compositing in Blackmagic Fusion.

I'm stuck in one place.

I'm compositing RAW passes as Octane manual says.
So it's Raw diffuse, reflection, refraction, transmision and their filters in the proper way.
And the result is fine, but it lacks fog.

I rendered the environment pass, but I have no idea how to composit it.
Any ideas on this one?
Maybe you know the workflow for Nuke? This would be helpful.

Thanks in advance!
