I am creating a flash banner but when I publish it (or export it) as gif, doesnt show all the layers. I am aware that the answer must be somewhere in this post Adobe Flash CS6 won't Export Animated Gif - How do on the main timeline? But I still do not understand it. Especially since the file is missing and I have no clue to what the users refer by 'frame 40' (i know it is a frame, I just dont know what makes this specific frame special). So do you have any advice to solve this issue?
I'm currently building a large gif file of timelapse of a building being constructed and it works no problems when exported. I would suggest you check thoroughly that all your layers that you want to see have their own animation frame assigned and also check the frame duration for the particular layer.
