V-Ray is a rendering plug-in for SketchUp. In addition to supporting most standard SketchUp features, V-Ray supports many third-party plug-ins. V-Ray for SketchUp includes two renderers, V-Ray and V-Ray Interactive.
V-Ray Production, which utilizes all V-Ray's features. Intended to be used to create a clean production ready render.
V-Ray Interactive, a fast active renderer. V-Ray Interactive can update the rendering as you make changes to the scene. V-Ray Interactive is intended to be used to both assist setting up the scene and produce Production renderings as well.
In order to use V-Ray, the render package must be enabled.
