For example, if the RGB values are 0.5, 0.4, and 0.0, then the monochrome value for any channel of that pixel would be 0.3. To determine the grayscale value for a channel, 3ds Max adds the values of of the red, green, and blue channels for each pixel and then divides by three. Monochrome Converts the color channel to grayscale.So, for example, red changes to cyan (green + blue) green changes to magenta (red + blue) and blue changes to yellow (red + green). The inverse for each channel is calculated by subtracting the value from the maximum value: 1.0 in the case of floating-point colors, or 255 for eight-bit channels. For example, if you set Blue=Red (Inverse), the blue component of each pixel takes on the inverse of the current value of the red component of that pixel. Red (Inverse)/Green (Inverse)/Blue (Inverse)/Alpha (Inverse) Replaces the channel with the inverse of the channel you choose.For example, if you set Blue=Red, the blue component of each pixel takes on the current value of the red component of that pixel. Red/Green/Blue/Alpha Replaces the channel with the channel you choose.Use the drop-down list to choose an replacement value or channel for each channel: Otherwise these fields show the current setting, such as Monochrome for the RGB channels. Available only when Custom is the active choice. Lets you specify channel operations on a per-channel basis. The previous settings remain active and available for changing. Choose the preset, and then choose Custom. Tip: You can use one of the preset channel operations (Normal/Monochrome/Invert) as a starting point for customization.
