Car Paint Materials & Studio

I’m trying to recreate the car paint materials that Ludvik explains in this tutorial: https://youtu.be/pkG3y5skAz0 with Cinema 4D. However, I am getting hung up on the portion where he creates a falloff node. The falloff node in 3ds max allows for channels to be mapped to its slots. However in Cinema, it is only a gradient ramp.

Also is the cellular node in 3ds max just a cell voronoi noise in Cinema?

One last thing… Can someone explain how he set up the studio in 3ds max? It seems to provide a lot of really nice reflections, so I’m curious how it’s set up.
