Operand A/B
The Operand menus, one for each output RGBA channel, allow you to set the desired input
information for the corresponding channel.
Red/Green/Blue/Alpha FG
Reads the color information of the foreground material.
Red/Green/Blue/Alpha BG
Reads the color information of the background material.
Black/White/Mid Gray
Sets the value of the channel to 0, 0.5, or 1.
Hue/Lightness/Saturation FG
Reads the color information of the foreground material, converts it into the HLS color
space, and puts the selected information into the corresponding channel.
Hue/Lightness/Saturation BG
Reads the color information of the background material, converts it into the HLS color
space, and puts the selected information into the corresponding channel.
Luminance FG
Reads the color information of the foreground material and calculates the luminance
value for the channel.
Luminance BG
Reads the color information of the background material and calculates the luminance
value for the channel.
X/Y/Z Position FG
Sets the value of the channel to the position of the pixel in 3D space. The vector
information is returned in eye space.
U/V/W Texture FG
Applies the texture space coordinates of the foreground material to the channels.
U/V/W EnvCoords FG
Applies the environment texture space coordinates to the channels. Use it upstream of
nodes modifying the environment texture coordinates like the Reflect 3D node.
X/Y/Z Normal
Sets the value of the channel to the selected axis of the normal vector. The vector is
returned in eye space.
Operation
Determines the Operation of how the operands are combined.
A: Uses Operand A only for the output channel.
B: Uses Operand B only for the output channel.
1-A: Subtracts the value of Operand A from 1.
1-B: Subtracts the value of Operand B from 1.
A+B: Adds the value of Operand A and B.
A-B: Subtracts the value of Operand B from A.
A*B: Multiplies the value of both Operands.
A/B: Divides the value of Operand B from A.
min(A,B): Compares the values of Operands A and B and returns the smaller one.
max(A,B): Compares the values of Operands A and B and returns the bigger one.
