So, I've been trying to edit a mod, lazybone's transformations. I know how to use the skillcreator and know how to edit bcms, but the bac is kicking my butt. Specifically the transformcontrol. I want to change the animation times a bit, so my main question is, how do the transformcontrol entries work? I figure duration is the duration in frames, but what exactly the starttime and other things with those entries?
Also, how do you determine which entry controls which transformation on multistage skills?

If there's a tutorial around that has some stuff about bac files please link it. I found a youtube video tutorial... but its in french... and youtube's translator is garbage. If it's written thats fine, I can use google translate, won't be perfect but it'll be legible.
