Not so bad, I'll find a way of doing it. To be honest, I also made some tries with that mission thing and the cutscene SEXP already in 3.6.7 and I just get an Idea of what I think would be cool

, so maybe it will be really a solution.
Damn shame those Cutrscene-SEXP are not fully functional, there are a lot of hard movements and the camera is hard to control (and mostly the subtitle SEXP doesn't offer much textspace and seems to missing some strings).
Just keep working on the endmovie things shade, I think it would be very good when a working code will find it's way into CVS.
