Render Studio: how to create atmospheric effects (such as rain, fog, smoke, haze)

mike_stanleymike_stanley Member Posts: 3 PRO
I'm modeling street lighting and trying to "see" the cone of light as if the light was passing through a light fog where the light is scattered by the fog.
I didn't see any options for changing the atmosphere. I created a big solid "glass with smoke" that represented the air, but couldn't get anything to work.
Any ideas?  Knowing that it isn't possible right now would also be helpful.

    I've not dug into Render Studio enough to know if it's capable of it, but "VDB" is your search term (Perhaps also "Scattering Medium"). Here's how it's done in Keyshot. Let me know if you figure it out!

    Another clue is that RenderStudio is based on Nvidia's Iray. I haven't tried any of this, but here's a tutorial from 2015 which may be relevant: https://www.deviantart.com/sickleyield/journal/Tutorial-Creating-Dust-And-Atmosphere-in-Iray-522291773

    This was linked off of the developer blog for Iray: https://blog.irayrender.com/archive

    I don't remember if that is specifically discussed in there but I found these "migenius" tutorials helpful. The interface looks a bit different now but the functionality is mostly identical so these are still relevant:

    @mike_stanley while this does not cover the topic fully, it should help you start the process towards generating some fog and a nice cone of light being emitted from your lamp. https://cad.onshape.com/help/Content/render-studio-interface.htm#add-volume 

    The best way to create that "atmosphere" is to generate a volume encapsulating your object, then you can define the environment in that volume!
