This page provides information on the Environment overrides rollout in the Render Settings.
Overview
The Environment rollout specifies colors or texture maps to be used during GI and reflection/refraction calculations. If a color/map is not specified, the background color specified in the Environment rollout of the current camera is used.
UI Path: ||Render Settings window|| > Overrides tab > Environment rollout
Parameters
Override Environment – When enabled, V-Ray overrides the default Maya environment and renders with the options selected below. Many options on this rollout appear only after this option is enabled.
Override Secondary Matte Environment – When enabled, V-Ray overrides the reflection/refraction environment for matte objects.
Background texture – Sets a color or a map to act as a background during rendering. Press the checkerboard button to select a texture. If a texture is selected, it will override the selected color.
GI texture – Sets a color or a map to be used during Indirect Illumination(GI) calculation. The effect of changing the GI texture is similar to skylight. Press the checkerboard button to select a texture. If a texture is selected, it will override the selected color.
Reflection texture – Sets a color or a texture to be used during calculations of reflections. Press the checkerboard button to select a texture. If a texture is selected, it will override the selected color. Starting with V-Ray 3.6, environment reflections can be previewed in V-Ray Material (VRayMtl) reflections with Viewport 2.0.
Refraction texture – Sets a color or a texture to be used during calculations of refractions. Press the checkerboard button to select a texture. If a texture is selected, it will override the selected color.
Secondary Matte texture – Sets a color or a texture to be used during calculations of reflections/refractions of matte objects. This option is available only when Override Secondary Matte Environment is enabled.
Show in viewport – When enabled, Maya displays one of the textures used to override the environment.
Use texture for – Sets exactly which texture will be displayed for the following options:
Background
GI
Reflection
Refraction
Secondary Matte
Options – Creates and/or selects the VRayEnvironmentPreview node, which allows more control over the viewport texture.
Create Sun – Creates a V-Ray Sun object in the scene. For more information, please see the V-Ray Sun and Sky System page under V-Ray Lights in this documentation.
Delete Sun – Deletes the V-Ray Sun object currently in the scene.
Create Sky – Creates a V-Ray Sky object in the scene. For more information, please see the V-Ray Sky Map page under V-Ray Textures in this documentation.
Delete Sky – Deletes the V-Ray Sky object currently in the scene.
