LoSboccacc 15 Posted January 28, 2022 anyone knows how this works internally? BIS_fnc_aircraftCatapultLaunch I wrote my launch script and works well however when the launch script ends inside the plane the gear is considered "up" but visually the gear remains down. guess BIS_fnc_aircraftCatapultLaunch runs some anymation on the model itself, and I wanted to peek at the magic to incorporate it.
