Anyone have good tips or a tutorial for atmospheric "God Rays" casting into interior spaces? Yes, I could paint it in Photoshop, but I am more interested in rendering out a separate pass in MR and compositing that in Photoshop. Then I would use that pass to paint them to the look I want.
I have briefly messed with the "Beam (Lume)" shader, and the "Parti Volume (Physics)" shader with little to no luck. I am not sure if that is the direction to keep working with, or if I should look elsewhere.
Below is a link to an extreme example of what I am trying to create.
