I'm making a short film with an alien in, the alien will be an actor with a latex mask covering most of his head (except his mouth.)
My plan is to give the mask green screen eyes and tracking markers, so that in post I can use the markers to track the position of the eyes (while still being able to rotate them) and the green screen to mask them in so they fit.
I've not seen any tutorials other than basic tracking that would help me here. It's a bit of a puzzle, so any thoughts on how to go about making it would be fantastic. Also any concerns or things you think I should be careful of are very welcome.
I've included a rough sketch of what I mean, hopefully it makes sense.
Thanks a bunch for any help in advance!
