Color Mapping

The Function of Color Mapping

Color mapping is used to adjust how color is actually displayed for a given image. When V-Ray determines a color value for a given pixel this value is then interpreted based on the type of mappings in use. This is very useful for minimizing the amount of an image which is out of the range of what can be displayed on a monitor.

Types of Color Mapping

Open Color Mapping under Options, V-Ray default is set to Reinhard option.

Types of Color Mapping

Reinhard is a blend between Exponential Mapping and Linear Mapping. The result is linear mapping when the Burn value is 1.0; and when it is 0.0, the result is Exponential Mapping.

Color Mapping examples

Color Mapping examples

Linear Multiply simply means that the color will not be changed from the generated value to the displayed value, like The image on the left.

Exponential is using color intensity to control brightness and prevent a wash out situation, but objects' color will become light, like the image on the right.

Color Mapping examples

HSV Exponential and Exponential are very similar, but will keep the tune and intensity of the color, like the image on the bottom left.

Intensity Exponential can maintain the RGB ratio, and will only affect the color intensity, like the image on the bottom right.

Color Mapping examples

Gamma Correction applied to the color a gamma curve. Dark Multiplier is a multiplier for the colors before they are gamma corrected. The inverse of the gamma value is the Bright Multiplies (gamma 2.2 should be 0.4545 in Bright Multiplier). The image is shown on the bottom left.

Instead of applying a gamma curve to each channel (RGB) independently, Intensity Gamma is applied to the saturation of the color. The image is shown on the bottom right.

Skatter is Your Best Friend

From small carpets in a living room to large scale forests, Skatter is designed to help you achieve the final look fast and easy.

Render Unlimited Amounts of Objects
