The Maya-Zest site takes a look at creating crepuscular rays, or visible shafts of light in V-Ray for Maya, showing how to create the effect using V-Ray’s volumetric lights and fog. This is not that difficult to create, however as the site notes, there is hardly any information on how to set this up in V-Ray.
This is not that hard to accomplish but no one ever writes tutorials on it! How frustrating… here is how to do it
The tutorial guides you through creating visible rays in V-Ray for Maya, but really, V-Ray is V-ray everywhere pretty much and I would imagine that the process would be similar using V-Ray in Max and Cinema 4D. Check out the tutorial for How to make volumetric lights and fog in V-ray here.
