General

The Environment section in VRAYforC4D render parameters is where you can specify a color and a texture map to be used during GI and reflection/refraction calculations. This group allows you choose Environment settings for indirect illumination calculations.

Parameters

Background 

Background color - lets you specify the environment color.

 

Brightness - a multiplier for the color value. Note that the multiplier does not affect the environment texture (if present).

 

Texture - lets you choose a GI environment texture. Note that if present, the texture overrides the specified Background Color.

 

Multiplier - a multiplier for the texture value.

 

Map type - allow you to choose type of apply of texture map.

 

Offset U - allows you to adjust the environment texture placement in horizontal direction.

 

Offset V - allows you to adjust the environment texture placement in vertical direction.

 

Don`t affect GI enc. color - when this option is on Background color has no effect on GI env.override value.

Global Illumination

This group allows you to override Environment settings for indirect illumination calculations. The effect of changing the GI environment is similar to sky light.

 

GI env. override - lets you specify the environment light color. Note that this is ignored if there is an environment texture specified.

 

Brightness - a multiplier for the GI env. override value. Note that the multiplier does not affect the Texture (if present).

 

Texture - lets you choose a GI environment texture. Note that if present, the texture overrides the specified GI env. override Color.

 

Multiplier - a multiplier for the Texture value.

 

Map type - allow you to choose type of apply of texture map.

 

Offset U - allows you to adjust the GI override texture placement in horizontal direction.

 

Offset V - allows you to adjust the GI override texture placement in vertical direction.

Reflection

This group allows you to override environment settings when reflections and refractions are calculated. Note that you can also override the reflection/refraction environment on a per material basis (see VRAYforC4D Materials section). 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.

Reflection env. override - lets you specify the environment color for reflections/refractions. This is ignored, if there is an texture specified.

 

Brightness - a multiplier for the Reflection env. override value. Note that the multiplier does not affect the Texture (if present).

 

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

 

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.

 

Map type - allow you to choose type of apply of texture map.

 

Offset U - allows you to adjust the reflection texture placement in horizontal direction.

 

Offset V - allows you to adjust the reflection texture placement in vertical direction.

Refraction

This group allows to override the environment for refraction rays only. When this override is disabled, VRAYforC4D will use the environment specified in the Reflection/refraction group when calculating refractions.

Refraction env. override - specifies the environment color for refractions. This color is ignored if there is an  texture specified.

 

Brightness - a multiplier for the Refraction env. override value. Note that the multiplier does not affect the Texture (if present).

 

Texture - lets you choose a GI environment texture. Note that if present, the texture overrides the specified Refraction env. override color.

 

Multiplier - a multiplier for the Texture value.

 

Map type - allow you to choose type of apply of texture map.

 

Offset U - allows you to adjust the refraction texture placement in horizontal direction.

 

Offset V - allows you to adjust the refraction texture placement in vertical direction.
