Ok... Some more notes..
It seems that IK Solver Limb version breaks the animation system. No animations will work. I do not know what version of IK handles the old version of Max uses that is in the SDK concerning the Jetway. I tried animating the IK Solver, gave it the Animation input via the Animation Manager. Also did that with the Arm, lower arm, and wrist, as well as the IK solver handle, and that did nothing.. Just sat there. I also linked the IK solver to the throttle. The throttle wouldnt animate because all animations broke with the IK solver in it.
Taking the IK solver out (deleting it) fixed the animations. Even if the pilot was 'not' exported but the IK Solver was still in there, it broke all animations, lol.. Also, upon deleting the IK solver, the wrist would no longer 'hinge' the forearm. His forarm just bends in half, like a U-shaped object. Early version save point, before the IK solver is applied, the wrist will 'hinge' the arm at the elbow like normal. So the IK Solver will break that if you apply that to the arm then delete it later.
For me, deleting the entire pilot fixed the animations problem. So you cannot do IK solvers on a pilot. Maybe you can with an Avatar.
Also, on the Jetway, you give your IK Handle (what they call it in the FSX SDK) a specific name for each IK handle. That and you need bones to have specific XYZ checks in their IK settings in the Hierarchy settings. Again, this is for the Bones only.
I finally decided to watch the entire video by Chuck Jodry on animating a rigged pilot. I think I watched it 2 or three times via re-winding things and bits. He uses multiple joints on the arms so that you have sideways movement (right and left input) and hinging (forward and backwards movement) all mixed together for the joystick controls. No IK Solvers.
Note that in Chucks tutorial on YouTube, he does not use IK solvers, he does not have special 'name tags' for joints. They are assigned their normal Animation points via the Animation Manager system.
I hate to fold and put my cards in and call this a loss. I do not want to go on with this another week. I invested what I think is my max time on this and I am not happy. The more I dug for answers, the more I got questions and problems. So I am at a bit of a loss. Maybe one more day and then I am walking away from this. Goodness. How hard can it be?? lolol...
