This page provides information on V-Ray as a plugin to Revit, as well as on rendering with it.
## **V-Ray in Revit**
---
V-Ray is a rendering plugin for Revit. It adds support for all Revit lights, geometric objects and materials and also introduces a set of features entirely new for Revit itself.
V-Ray is seamlessly integrated in Revit and all its options are available from within the Revit user interface, including Global Illumination and the creation of V-Ray materials, maps and lights. While V-Ray renders standard Revit features, the V-Ray options are designed to work with the V-Ray render engine, and thus improve both image quality and render times.
V-Ray includes two engines: a CPU based and a GPU based. V-Ray renderings display in the[ V-Ray Virtual Frame Buffer](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/160465097) (VFB), which has a multitude of V-Ray specific tools for saving and comparing renderings, adding lens effects, and viewing render elements.
For tools to adjust rendering quality and speed with V-Ray and V-Ray GPU, see the [Renderer](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/161611958) page.
## **Rendering with V-Ray**
---
Both V-Ray and V-Ray GPU engines support **Production** and **Interactive** Rendering modes. The Production Rendering mode utilizes all V-Ray's features and is intended to be used to create a clean production ready render.
The Interactive Rendering mode is a fast active renderer that updates the rendered image as changes are made to the Revit model or the V-Ray settings.
The Interactive renderer always runs in **Progressive** mode, an image sampling mode that progressively refines the image over time. The **Production **rendering mode switches between Progressive and Bucket image sampler. Unlike the Progressive image sampler, the **Bucket** one takes a variable number of samples per pixel depending on the difference in the intensity of the pixel, as result the image is rendered on small square portions (called "buckets").
Use V-Ray [Swarm ](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/160563336)distributed rendering system or render in [Chaos Cloud](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/162103426), as a complement to or a substitution of your usual render workflow.
Preview your projects in real time with [V-Ray Vision](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/162136187), which provides better lighting and material representation as well as camera animation playback controls.
> ⚠️ When rendering in Interactive mode in some specific cases and using the native Revit Undo/Redo command, the Interactive rendering stops and the Undo/Redo command has a priority.
