V-Ray UI

This section allows you to control some of the V-Ray User Interface within Maya.

UI Path: ||Render Settings window|| > Settings tab > VRay UI rollout

Add/Remove – Adds or removes V-Ray specific buttons in the Maya Rendering shelf.

Create/Replace V-Ray Shelf – Adds a V-Ray shelf which contains functionality from the Create menu and the Render Settings dialog. For more information, please see the V-Ray Shelf page.

Render swatches for VRayMtl and V-Ray lights – When enabled, V-Ray will render a small preview in the swatches for V-Ray materials and V-Ray Lights.

Swatch Background – Specifies the preview swatch's background color/map when the Use default background checkbox is disabled.

Clamp viewport shader opacity – Keeps objects with opacity and/or refractive properties from being able to go to 100% which would cause them to become invisible in the viewport.

Show environment reflections in Viewport 2 – When enabled, reflects the Environment Reflection texture in the Viewport 2.0 preview of V-Ray shaders.

Compute heavy procedural textures in Viewport 2.0 – When enabled, it allows heavy textures (e.g. Bercon Noise) to be shown in Maya's Viewport 2.0 (if Maya's Viewport option Textured is enabled as well). Note that this option works for Windows and Linux only. Some Bercon Noise features are unsupported/partially supported in preview. This option is disabled by default, because heavy textures can be slow to draw.

Check for updates – When enabled, V-Ray will check for updates when Maya is started. When a newer version is available, an "update available" notification appears in the Render Settings and the VFB window. Clicking the notification icon will provide more details and download links for the new version.

Viewport shader quality – Controls globally the VRayMtl's quality in the viewport. Each individual VRayMtl's viewport shading quality can also be controlled.

Low – Renders only the direct diffuse and specular (Fresnel, metalness and specular BRDFs) components.
Medium – In addition to the ones rendered with Low setting, it includes environment sampling (reflections and refractions), sheen and coat.
High – In addition to the ones rendered with Medium settings, includes normal/bump mapping, diffuse roughness and GTR gamma other than 2.0.
