MAJOR discovery (for me anyhow) for us animators. The wayward spline fix is here. If you want to convert any or all frames to Linear Interpolation (to rid of unwanted overshoots between keys) ,Here's a very simple way: 1)In the Animation Pallette drag a box over the offending frames & Body part for the messed up in-between frames 2)Click on the Linear Interpolation gadget in the upper right of the Anim Pallette window (see image). Thats it! All the selected frames convert to Linear Interpolation. This ends hours & days of my struggles fixing movement of frames that are suppose to be "Inbetween" keyframes, but are anything but. I never thought of this, someone else may have I'm sure. I spent so many hours searching through each MT dial in the Graph Window, limb by limb, MT dial by MT dial(Bend,Twist, XRot etc), to convert to Linear Interpolation or to see what went wacko on me. Just select/drag a box around (in the Animation Pallette Window)the offending frames for the wacky keyframes/inbetweens, for the bodypart, & hit the Linear button.
