How it Works:
After running the script it will check 3 conditions (checkboxes) and if all of them are accepted (which in that case they will be displayed in green) then you can use the button < “Remove Color Cast” > to run the calculations and then the frame buffer color tint will be affected accordingly.
You may use intensity before or after hitting the < “Remove Color Cast” > button to change the intensity of the effect.
The 3 mentioned conditions are:
1- Corona renderer must be your selected render engine. Also, you can click on the text of this condition to set the render engine automatically.
2- Elapsed render passes need to be at least 2 to run the script. It does not matter if it is an interactive render or the final production render. and because of this script use frame buffer content, it must not be empty and a render need to be in there (VFB)
3- the VFB color tint needs to be pure white (RGB 255 255 255) to use this script. Also, you may click on text of this condition to set frame buffer color tint to pure white.
if you click on any 3 color boxes next to the < “Remove Color Cast” > button then the color of that box will apply to the Frame Buffer color tint option. the last one (right box) is always white so you use this to set the color tint option to pure white as well.
