Selects the RGB Multiply map type and adds it to the current material in the Material Editor sample window.
The RGB Multiply Map is typically used for bump maps, where you might want to combine two maps to achieve the correct result.
This map combines two maps by multiplying their RGB values. For each pixel, the red of one map is multiplied times the red of the second map, the blue times the blue, and the green times the green.
If the maps have alpha channels, RGB Multiply can output either map’s alpha channel, or a new alpha channel created by multiplying the alpha channel values of the two maps.
You can also make one of the maps a solid color. This tints the other map.
These are the controls in the RGB Multiply Parameters rollout:
Color #1 and Color #2: Click a map button to assign one of the maps. The check box disables or enables the map. To tint one of the maps, turn off the other map and click its color swatch to choose the tint color, using .
The radio buttons in this area choose how to generate alpha for the map. If neither map has an alpha channel, these options have no effect.
Map #1: Use the first map’s alpha channel.
Map #2: Use the second map’s alpha channel.
Multiply Alphas: Generate a new alpha channel by multiplying the alpha channels of the two maps.
