I would like a shader that works like Muddymole's Saturation Mask but I was wonder if it would also be possible to add a user set parameters like
Saturation = value (anything covered in mask would be set to this) ?
This would enable the option of doing effects with oversaturation like this:
(maybe it would be better to switch it around ie. anything not covered in mask gets set to saturation)
Pinging @MuddyMole since you made this and I'm linking to your file (hope this is ok).
