i have several keys that animate a cranes motion.  is there a way to have the whole thing just reverse back to start or do i need to copy each key?
Thanks

Hi there,

Just select the keys you wish to switch round and holding shift move each frame e.g the first frame to the last and the last frame to the fist and switch around the frames inbetween.
Your animation should now play in reverse.

Hope this helps

Select all the keys and shift+copy them, then use the Reverse Time feature of the Dope Sheet.

Louis does something on the timeline where he reverses the keys just with some dragging of handles.  I definitely need to watch the video again just to learn how he turned on this functionality.  It definitely looks easy though.

select all the keys and grab from the front and pull them forward turning them inside out so to speak

You need enough space in the animation bar; select all the animation keys,
Drag the white square towards the end of the animation bar (in the attached example from frame 0 to frame 200).
The animation is reversed. You can move it back again.

I tried to drag the time range across - as you’ve said, but I get the following error:

This operation is not possible because it results in illegal timing.
Some restrictions are:
-keys on the same track cannot overlap or pass one another
-no keys before the first or after the last footstep
-no keys in negative frames

I was trying to reverse a walk animation for a character, grabbed the bip, selected the range from 0-130 frames, and dragged the left corner over to frame 260, as Ivan has said, got that error.

I’ve never tried it with Walk Animations, as far as I know it doesn’t work.
Anyway it is working for me without issues by any “standard” animation as well
by rendered (baked) reactor animations.
Try the Reverse Time option in the track view; don’t know if it is working in case like yours either, bur give it a try.

Hi Ivan,
Thanks for responding.  I’ve been unable to use the reverse time option in the dope sheet,
in fact, the option is grayed out and unselectable.  Sometimes it is selectable, and I use it,
but it doesn’t do anything.  I’ve heard others say that reverse time does not work.
