I cant for the life of me figure out the gizmos for the character joint twist and swing axes. The documentation tells me that the orange axis is the twist axis, while the green axis is swing1. A further non-displayed axis perpendicular to both is swing2. My intuition tells me that the twist axis should be a line about which the object in question rotates. If its an arm, for example, the twist axis should be parallel to the length of the arm. In Unity 2.5, these axes are completely out of whack. In the attached image, I have made two objects connected by a character joint. As it stands, he hanging capsule is constrained to swinging left and right only - no twist and no swing2. You can see in the attached image that the orange twist-axis gizmo (centered in the cube) is pointing in a direction that seemingly has nothing to do with twist, while the green swing axis gizmo seems to be pointing down the length of the capsule, in what to my mind should be the twist axis. Have I completely misunderstood what these axes represent? Actually, these gizmos would be better represented by coloured arc/wedges showing the upper and lower limits of motion. They would be much easier to see like that, and the information represented would be more informative.
