I just thought I would ask that, the manual suggests it as a last resort. Im curious if it would help in this situation as I've never used it and can't, off the top of my head, imagine a scenario where one would need it. (not being sure how it affects the timeline) I've got some epxerience with the animation palette so lemme give it a wirl. Hopefully I understand your post enough to visualize both your functions and resulting problem. ahem A few notes first: Spline interpolating needs 3 keyframes to work properly. If you only have two, your motion will be distorted, ie: going way past the end frame near the middle of the action and then snaping back to rest at the last keyframe. This can be advantageous in some cases especially in cunjunction with the graph but takes alot of learning to get it right and to understand the dynamics of how it reacts to certain moves. Linear interpolation is a straight line. Two keyframes are fine but youll still only get a linear motion. You can add three keyframes but then you would get a snap and the second keyframe as it continues to its end-position. I use a combination of spline, breaks and linear keyframing. I don't think anyone could make any animation of any significance without using a combination. (who knows though, im only 1 guy) This may require some backstepping in your timeline in order to sequence a proper set of keyframes and tweens. Droping the arm. I think the first thing I would do in this case is find my 'end-frame' for my 'hold' position. (the arms being crossed) I would add a keyframe right there in the collar and make it linear. You could break that spline instead then continue with a new spline. (try that and see if that works for you) But I would go-go linear only because it makes changes easier later on if needed. (depending on what they are of course) Then I would scootch over about 5 more frame in the collar and add another keyframe, Linear to. What I'm doing now is closing those 5 frames as 'zero-motion'. It shouldnt move at all within those 5 frames and anything after it, shouldn't affect it. (not that it takes 5 frames to do that, thats completly arbitrary. the point is that the linear frame has broken itself away from the spline before it. a break spline keyframe might do the same thing and then you might be able to continue along with a new spline and be okay, i dont know, I've never had ocassion to do that specifically) Then it would only be a matter of adding a new keyframe, linear at the start of my move then one for about 5-20 frames before the end. Then I would add a few frames of 'wiggle' or 'ease'. Make those 'ease' frames regular splines. (default) one at the end of your linear and then scootch about 5-20 frames (whatever you decide) and drop another keyframe in. This will end the spline. This will add a smoother transition from the end-frame of my linear motion to the end-frame of my spline motion, which shouldnt be to drastic of a move anyways. Hope this helps! Good luck!
