Hey!
Upon activating that setting, The oculus quest 2 goes mad 
It really becomes unusable. I tried to create the volumetric and the atmospheric fog… and no luck on standalone, after some research I learned that that isn’t really possible.
Even tried doing it through materials, which actually looks pretty awesome and is super light to run on the pc, but still not able to run it on standalone quest 2.
The solution was to build the project and have it being cast to the oculus through cable, using the processing and graphics of the pc.
If you do have any other ideas, techniques or tips… they are always welcome!
Thanks for reaching out!
