The VRayTemperature 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.
Color 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.
Red – Specifies the value for the Red channel. Note that the full intensity is reached at 1.0 for this parameter (and not 255).
Green – Specifies the value for the Green channel. Note that the full intensity is reached at 1.0 for this parameter (and not 255).
Blue – Specifies the value for the Blue channel. Note that the full intensity is reached at 1.0 for this parameter (and not 255).
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).
Color – This color swatch can be used to visualize the resulting color. It can also be double-clicked to bring up the standard Maya color chooser.
Gamma – Specifies a gamma correction applied during rendering. This does not affect the Color swatch.
