I have only been using Nuke for a few weeks, so any help would be greatly appreciated.
I am trying to remove the normal blue and white sky, and replace it with a red sky on 190 frames.
I am using the Bezier tool but I cannot find the right merge settings (mask, overlay, add).
Please can someone advise which setting I have to use?
Please look here for a screen shot and a clearer picture:
Thank you in advance,
