View Full Version : Graph Editor troubles

05-07-2008, 03:02 AM
I'm quite new to Lightwave and struggling very much with it. I am making a walk cycle and I need to know how to use the graph editor to make it a continuous cycle for about 22 steps.

You animate just one cycle then allow it to repeat using Pre and Post Behaviour in the Graph Editor.

William Vaughan did a good basic walk-cycle tutorial which you can find here:

The movie is here:


A listing of all the tutorials by William Vaughan - scroll down until you find a section on Character Animation and then find the movie 'Animating a basic walk cycle'.

If you right-click and 'Save Target As...' from the first link I gave you, that might have worked - try that anyway.

This movie will help more than me explaining it here :)

that didn't say anything about pre and post behaviours

Well OK - I thought it did - one of them does.

Right, so simply then, a post behaviour causes a group of keyframes to repeat, or oscillate, or remain constant as of the last keyframe of the group.

Try it.

Create a Null, or use the Camera, doesn't matter - set three keyframes on just one axis.

So on X, say, set a keyframe at frame 1 to be 1m, another at frame 10 to be 0m, then a third at frame 20 to be 2m. Right click drag around all the keyframes then select each option in the Post Behaviour menu and watch what happens.

With a walk cycle, you animate one cycle, that ends where it started, then do the above on that to have the cycle repeat.
