It is about three years ago that I figured out how to make animations with more than 1024 frames for FS2004. But until now the only explanation other developers had on how this works was this quick forum post I made. I admit it is a bit late, but I have finally finished the tutorial that explains the process in a more detail. I also try to explain how the animations work, hopefully it makes sense. A bit thanks to all the forum users who kept asking questions about this, that is what made sure I finished the tutorial by now.
