Trying to make fog effect

[Leandro Oliveira]

Hi,

I´ve tried to make fog effect in my scene, but no success. I used this Dravia video (https://youtu.be/gvo9WLBqNVU) as a guide, but I can´t see the effect.

I´m running Lux 2.5 Daily Built from January 19th on Blender 2.91.

Scene attached.

Thanks,

Here:

Note, Fog's Interior Volume is Corridor's Exterior Volume.
Take care

Thank you, kintuX!

@kintuX, I noted that you used a valor of 5 for priority, on Heterogenous Volume node. What is it for?

From documentation:

Volume Priority

Volumes have a priority setting, which is an integer number.
In regions where volumes overlap, the volume with highest priority is chosen and replaces all other volumes.

Hey, Leandro. You can also check this file with simple homo- and heterogen volume.

Thank you very much, DionXein! I´m studying your file, too.

Pay your attention to Camera's volume auto-detect. With premade volumes no need in Fog object. But in example from @kintuX Camera volume autodetects happens from Corridor exterior volume(because it have only inner normals direction).

So, for atmospheric volumes, I have to use always a volume connected to the camera, right?
