This page provides information on the V-Ray TexTemperature node. Overview The V-Ray Temperature texture map is typically used in conjunction with specific light sources to emulate a specific value, like a Kelvin temperature. This is very useful for different parts of  mesh lights , or to map the color of  V-Ray Light Material  changing from a warm to cool value. Parameters Mode  – Specifies the mode in which the color is determined:   Color  – The color is directly specified by the  Color  parameter. Temperature  – The color temperature (in Kelvin) is specified by the  Temperature  parameter.  Temperature  – Specifies the temperature in Kelvin. Color  – Specifies the texture color. RGB Multiplier  – Specifies a multiplier for the color strength. Alpha  – Specifies the value for the Alpha channel. Note that the full intensity is reached at 1.0 for this parameter (and not 255). Gamma Correction  – Specifies a gamma correction applied during rendering. This does not affect the Color swatch. Common Uses    In each example below, the sphere lights have the same  V-Ray Light  applied to them. A V-Ray Temperature texture map is applied to the V-Ray Light material to show various color temperatures between each example image. The Temperature texture has  Mode  set to  Temperature . In the final image below, five separate V-Ray Temperature texture maps were used, each with a different color temperature to show a variation. No other changes were made to the  V-Ray Light .   Mode  =  Temperature   Temperature  = 4000.000   Mode  =  Temperature   Temperature  = 2700.000   Mode  =  Temperature   Temperature  = 10000.000   Each mesh lights uses a different BRDFLight material & Temperature texture,  each with its  Mode  set to a different  Temperature  value
