Come on Cricky!
First, thanks for doing it! It seems it was not a case of "deciphering" after all, because you made it and are giving it away! Good!
I am a teacher Cricky! I am a 3D video production teacher, so I learned: To teach you must make learners, go step by step! I bet, those who will "decipher" and try to make their OWN FADER will learn a lot much more, by "deciphering" my "Da Vinci" code than by downloading the FADER already done!
Of course, those who already know how to do it, might do better by taking your offer and getting it already done! But... It is so easy! really! It might take longer to download than to simply make it! (Paradox of Life!)
I agree the trick with the lights will do sort of the same, except you can not do layered dissolve as I propose. Right?
Thank you for not leaving me alone in this. It is good to be motivated as to explain better and to learn more!
