Hi there,

the typical premultiply problem! I know.
In Shake i would use mdiv the color corrector and then mmult. But how do i get this solved in Fusion?

channel boolean, divide RGB with alpha and leave the alpha alone. Do your CC and then put another channel boolean and set it to multiply with the alpha instead.

Or you can use the Custom tool and divide each channel with the alpha RGB/A , do CC and then do another Custom tool and multiply with alpha RGB*A.

Or you can use the free drUtils thats already got a mdiv mmult node.

.....or you can use fuses to write your own :)

If you are using the Color Corrector node, under the options tab is a pre-divide and post-multiply option. Brightness/contrast, color curves, color gain all have it listed under the main tab at the bottom of the controls.
