Prop pitch, in addition to being important inside the engine model, changes the sound of the prop. Unlike aircraft pitch (and yaw), which increases one blade pitch and reduce the other, the prop pitch itself modifies both values. Therefore, the sound system would like to have the exported value available - if only for future reference. As far as I'm concerned, the outside view is purely for entertainment since there is nothing realistic about hanging a couple dozen feet behind the aircraft in the open air, operating the controls remotely. Since articulating that 3D model is cheap (happening at the scene graph parse time) compared to other value adds (most of which need textures) I encourage people to put as much articulation in the system as possible. There are two specific exceptions ot the entertainment-only concept. First, for review of a maneuver by the instructor and student pilot, in which case items such as gear extension are crucially important because the pilot has no direct control over them and infers action. Second, for instructor monitoring of a potentially remote student, in which case it might be easier to watch from outside the plane. In addition to prop pitch: When we put a 3D human inside the cockpit, please have the head articulate to match the view direction. Also, plan ahead to connect the navigation, landing, taxi, anticollision, strobe, cockpit, panel, nightglow (I've probably missed some) light switches on the cockpit panel to associated features in the model. Finally, is now a good time to mention the operating system specific pilot 3D model, with the passenger seats (to the extent available) filled with the 3D models of our other supported operating systems ? All it needs is for the model to have hooks indicating seat positions, and a model directory in the base with one model per operating system. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
