This page provides information about the real-time viewer V-Ray Vision.

Overview

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 as well as camera animation playback controls.
In addition to its main function as a viewer, V-Ray Vision can produce spherical panoramas and quick output of both still frames and animation sequences. It comes with its very own auto-exposure, tonemapping, and color correction options.

When V-Ray Vision is launched, it automatically loads the current SketchUp 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 SketchUp scene.
Stopping the live link, by either clicking the SketchUp toolbar's V-Ray Vision button or any of V-Ray's Render buttons, ends the connection but does not clear the loaded scene. To stop V-Ray Vision, close its window.

In addition to loading scenes directly from SketchUp, 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.

See theV-Ray Vision tutorial or the Courseware page for more information.

Settings

Quality

Enable Proxy LOD – Enables the LOD switching for Proxy Mesh assets. The full mesh is visible up close, whereas the proxy preview mesh is displayed in distance. Note that both share materials.

High quality Cosmos Assets – Displays a high quality version of each Cosmos asset close to the camera. Cosmos assets have multiple levels of detail and by default Vision loads lighter meshes for increased performance. When this option is enabled the highest level will be used when the camera is close to the object. Note that enabling this option might have major impact on performance and loading time depending on the assets used. The scene will be automatically reloaded when the option is changed which might take a while depending on the project's complexity.

Shadows Quality – Controls the quality of Sun, Directional, Omni and Spot lights. From the drop-down you can choose from:

Low – Low quality shadow map filtering is used. Shadow map size is decreased during scene interactions.
Medium – Medium quality shadow map filtering is used. Soft shadows are disabled.
High – High quality shadow map filtering is used. Soft shadows are supported. Changing the Sun size affects the shadow softness.

Temporal Anti-aliasingEnables a higher quality anti-aliasing method. Note that this is a compute expensive option and needs multiple frames to achieve good-looking results.

Camera

Auto Exposure1 – Enables auto exposure.

EV Compensation – Multiplies the exposure value of the camera or the value calculated by the Auto Exposure (when active). This option can store two independent values based on whether Auto Exposure is active.

Navigation

Fly Mode – Changes the view navigation mode. Use the W, A, S, D, Q, E keys on the keyboard to move around. Holding down Space temporarily increases the movement speed. Hold the Left Mouse Button to look around.

Free FlightIn free flight the forward movement of the camera is determined by the view direction. When disabled, the vertical camera orientation is ignored and the movement is constrained to the horizontal plane.

Fly Speed (m/s)– The movement speed measured in meters per second. Only has an effect in Fly mode.

Mouse Sensitivity– Changes the mouse speed when looking around in Fly Mode.

Smooth Movement Delay– The time it takes the camera to gradually cease after being moved during Fly Mode. Calculated in seconds.

Lighting

Automatic IBL Sun– Automatically adds a directional light based on the brightest spot in an HDR image. The option has no effect if the project Sun is enabled. It is not recommended to enable it if there is no single distinct bright spot in the image used for lighting.

Ambient Light ModeEnables the ambient lighting mode. This mode can be used to remove the blue sky tint from interior renders. When enabled, the project's environment will remain visible in the background but will no longer affect the diffuse indirect illumination and the reflections. An ambient white/gray color will be used as indirect environment. Note that the state of this parameter will not be saved with the project and has to be manually set.

Ambient Light IntensityControls the intensity of the ambient lighting. Note that the value of this parameter will not be saved with the project and has to be manually set.

Ambient Light Intensity value between 100 and 200 is sufficient for interior renders when using Sun and Sky.

FAQ

Does V-Ray 5 include Vision?

Yes, Vision is integrated in V-Ray 5 for SketchUp. It can be launched directly from the main V-Ray toolbar.

What is the difference between Vision and Chaos Vantage?

How do you see both engines develop in the future?

V-Ray Vision is a feature of V-Ray for SketchUp, Rhino and Revit, while Vantage is a standalone application that can import and render V-Ray data. The technologies used differ quite significantly as well.

Vision is a rasterizer, a game engine meant to be used as a real-time scene viewer. It can also output final images or animations when the quality is sufficient for the project presentation.

Vantage is a real-time ray-tracer which makes it a lot more powerful in some regards. The lighting quality as well as reflections, refractions and other complex effects are calculated with high accuracy. Heavy models (in terms of polygonal count) are also not a problem for Vantage. Also note that Vantage requires a DXR compatible GPU (NVIDIA RTX only), while Vision runs on any GPU that supports DirectX 11 or 12 and Shader Model 5.0 (both NVIDIA and AMD cards can be used).

A common design shared between Vision and Vantage is that they visualize standard V-Ray Lights, materials and other effects. There is no need to modify your scene in order to use one of the engines. Future plans include Vision to be extended in terms of its presentation capabilities, V-Ray effects support and lighting quality while keeping the high framerate a priority.

Does V-Ray Vision work on macOS?

Yes. Make sure you use V-Ray 5.1 or a more recent V-Ray version and launch Vision from the main V-Ray toolbar.

What is the reason for lighting and material differences between Vision and the production V-Ray render engine?

• The technology used in Vision (rasterization) is fast but limited in quality and number of effects that can be supported.
• Most of the common material parameters used in V-Ray are supported in Vision. Some are still unsupported and hence you’ll see some differences in the way surfaces appear.
• Vision is also still not capable of evaluating the global illumination in the scene. As a result closed interior spaces would be illuminated incorrectly in most cases. Calculating many light bounces is required for better results.
• Chaos' main goal with Vision is to give a real-time experience keeping a high framerate.Vision is in active development, so the supported features are subject to change.

1- Note that when Auto Exposure is enabled, sizeable very dark or light portions of the buffer (e.g. completely black background surrounding a model), might produce an exaggerated exposure value adjustment.

2- To successfully open a standalone executable Vision file on Apple M1 systems, make sure to enable the 'Open using Rosetta' option from the file's info window.

  • V-Ray Vision is part of V-Ray for SketchUp and does not require additional licensing.
  • V-Ray Vision requires hardware capable of running DirectX 11 or DirectX 12 and Shader Model 5.0
  • Scenes with Chaos Cosmos assets can be rendered in V-Ray Vision.
  • Temporal Anti-aliasing is disabled when spherical panorama images are exported.
  • Sun and camera animations from Grasshopper can be rendered in Vision from manually exported .vrscene files. Note that object animations are currently unsupported.
  • The Always face camera option of SketchUp components is disregarded during Interactive rendering and Live Link.
