GPU Environment

The Environment section in V-Ray GPU render is where you can specify a color and a texture map to be used during GI and reflection/refraction calculations. If you don't specify a color/map then the background color and map specified in the 3ds Max Environment dialog will be used by default. The parameters in this rollout override the 3ds Max Environment settings.

UI Path: ||Render Setup window|| > V-Ray tab > Environment rollout (Renderer set to V-Ray GPU)

This group allows you to override the 3ds Max Environment settings for indirect illumination calculations. The effect of changing the GI environment is similar to skylight.

On – Turns on and off the GI environment override.

Color – Specifies the environment (skylight) color. The color is ignored if there is an environment texture specified.

Multiplier – A multiplier for the color value. Note that the multiplier does not affect the environment texture (if present). Use an Output  map to control the brightness of the environment map if the map itself does not have brightness controls.

Texture – Lets you choose a GI environment texture. Note that if present, the texture overrides the specified Color.

This group allows you to override the 3ds Max Environment settings when reflections and refractions are calculated. Note that you can also override the reflection/refraction environment on a per material basis (see VRayMtl) or a per map basis. If you do not enable the Refraction override, this group of controls affects both reflections and refractions. If you enable the Refraction override, then this group affects only reflections.

On – When enabled, V-Ray uses the specified Color and Texture during reflection/refraction calculations.

Color – Specifies the environment color for reflections/refractions. The color is ignored if there is an environment texture specified.

Multiplier – A multiplier for the color value. Note that the multiplier does not affect the environment texture (if present). Use an Output map to control the brightness of the environment map, if the map itself does not have brightness controls.

Texture – Allows you to choose an environment texture. Note that if specified, this texture overrides the Color.

This option allows the override of the environment for refraction rays only. When the override is disabled, V-Ray uses the environment specified in the Reflection/refraction environment when calculating refractions.

On – Enables the refraction environment override.

Color – Specifies the environment color for refractions. This color is ignored if there is an environment texture specified.

Multiplier – A multiplier for the Color value. Note that the multiplier does not affect the environment texture (if present). Use an Output map to control the brightness of the environment map, if the map itself does not have brightness controls.

Texture – Specifies the environment texture for refractions. Note that, if present, this texture overrides the specified Color.

This group allows you to control the appearance of matte objects in reflections/refractions.

On – When enabled, V-Ray uses the specified Color and Texture during reflection/refraction calculations.

Color – Allows you to specify the environment color for reflections/refractions. This is ignored, if there is an environment texture specified.

Multiplier – A multiplier for the color value. Note that the multiplier does not affect the environment texture (if present). Use an Output map to control the brightness of the environment map, if the map itself does not have brightness controls.

Texture – Allows you to choose an environment texture. Note that if specified, this texture overrides the Color.
