V-Ray Vision is a real-time viewer that can be used in any project set up for V-Ray rendering. It is a lightweight “game engine” (rasterizer) that does not currently use any type of ray-tracing. Due to its speed, it can serve as a powerful alternative viewport that provides better lighting and material representation. In addition to its main function as a viewer, V-Ray Vision can produce spherical panoramas and quick output of still frames. It comes with its very own auto-exposure, tone mapping, and color correction options. Furthermore, V-Ray Vision also supports Solar Studies (sun animations) exported from Revit.
When V-Ray Vision is launched, it automatically loads the current Revit project and starts an interactive session. This means that while it is running, a live link is established that sends to the viewer all updates made to the Revit project. Stopping the live link by clicking the Revit ribbon's V-Ray Vision button ends the connection but does not clear the loaded model. To stop V-Ray Vision, close its window.
In addition to loading models directly from Revit, V-Ray Vision is able to load .vrscene files directly. In this case, in order for the modifications to be displayed, the source file has to be reloaded.
V-Ray Vision can produce quick output of still frames, VR panoramas, image sequences as well as videos in .webm format.
