This page provides information on V-Ray as a plugin to 3ds Max.
Rendering with V-Ray
Once V-Ray or V-Ray GPU is selected as the renderer in 3ds Max, you can start rendering either in the viewport or in the V-Ray Virtual Frame Buffer (VFB), which provides a multitude of V-Ray specific tools for saving and comparing renders, adding lens effects, and viewing render elements. V-Ray allows you to choose your rendering mode (Production Rendering Mode or Interactive Production Rendering) as well as spread a render job across several computes via distributing rendering. It also comes with a range of tools that can adjust rendering quality and speed.
