Fix Map Contrast
|Top Previous Next|
Sometimes effect maps can develop a washed-out or low-contrast appearance. This node will automatically adjust the contrast of any effect maps passing through it to make use of the full tonal range from black to white. More information on effect maps in general can be found in the Using Effect Maps tutorial.
This node takes a single input. It won't affect the input image itself, but it will alter any effect maps present in this part of the texture, as described above.
This node has no properties.
