|
Minimum Threshold |
Defines the minimum RGBA value that can be attained before the input color is out of range. |
|
Input |
Defines the input texture or shader to key. |
|
Maximum Threshold |
Defines the maximum RGBA value that can be attained before the input color is out of range. |
|
Include Alpha |
Includes the alpha channel. |
|
Color if In Range |
Defines the In Range color as long as the input remains between the Minimum and Maximum Threshold parameters. |
|
Color if Outside Range |
Defines the color if the input falls out of the range set by the Minimum and Maximum Threshold parameters. |
This shader is almost always placed directly after (to the right of) a color output in order to isolate a range before it is input to a color parameter.
