Volumetric Fog Questions.

[leallolo]

Hello Octane Friends!

Im a new user, experimenting and having a blast using the engine, I need to admit I have a crush on Octane.

One of the things that really pulled me into it was the fast and beautiful volumetrics.

I have been struggling a little bit to fully understand what are the "best practices" to archive certain results.

For example, I have a few precise questions.

================================================

1. What is the best way to add fog to a NON-SUNLINT Scene. ( I know how to add volumetric fog to my scene using daylight sunlight or volume spotlight.)
what I'm looking for is something similar to the "Fog Volume Object" that I can see is available in c4d. The particular use is for something like an underground scene or Interior

2. the second question is related to how or what is the best way to map a 3d noise into that Volume

Thanks so much for any guidance!
