This page provides information on the Color Map.

Overview


The VRayColor texture map can be used to set any custom color and  also allows you to set a floating point value for the R, G, B, A channels. It can also be used to specify overall opacity for V-Ray Material | VRayMtl materials.  In the example shown the color was set to red.

Parameters



 

 

Color mode – Specifies the mode in which the color will be determined:   

Color – The color is directly specified by the Color parameter.
Temperature – The color temperature (in Kelvin) is specified by the Temperature parameter. 

Red – The value for the Red channel. Note that the full intensity is reached at 1.0 for this parameter (and not at 255). 

Green – The value for the Green channel. Note that the full intensity is reached at 1.0 for this parameter (and not at 255). 

Blue– The value for the Blue channel. Note that the full intensity is reached at 1.0 for this parameter (and not at 255).

RGB multiplier – The multiplier for the color.

Alpha – The value for the Alpha channel. Note that the full intensity is reached at 1.0 for this parameter (and not at 255). 

Color – This color swatch can be used to visualize the resulting color. It can be double-clicked it to bring up the standard 3ds Max color picker. Note, however, that the color picker is limited internally to a precision of 8 bits per channel and if modifying the color, the RGB components will snap to the nearest 8-bit level. 

Color gamma – A gamma correction that is applied during rendering but does not affect the Color swatch.

 

Gamma Correction


The VRayColor texture allows you to apply a gamma correction on the displayed colors. Note that this correction is applied only to the displayed color swatch for the  Color  parameter. The gamma value does  not affect the actual RGB values in any way. The gamma correction controls are shared by all instances of the VRayColor texture – if you change them in one VRayColor texture, all other VRayColor textures will automatically pick the new values.

Gamma correction – Specifies how to determine if and what gamma correction to apply: 

None – No gamma correction is applied on the displayed color.
Specify – The gamma value is explicitly specified by the  Gamma value  parameter.
3ds Max – The proper gamma value is derived from the 3ds Max gamma settings as set in the 3ds Max Preferences  dialog.

Gamma value – Specifies the gamma correction value in the case when the  Gamma correction parameter is set to Specify.

 

Notes


  •  Black color is represented as  0.0,  0.0,  0.0 for the  Red, Green and Blue parameters respectively, white is represented as  1.0,  1.0,  1.0, and middle gray as  0.5,  0.5,  0.5
  •  The Alpha parameter has no effect when the VRayColor map is used in the opacity slot of a  VRayMtl material. In this case the opacity value is calculated with the formula: opacity = (R+G+B) / 3.
