DT walk cycle tutorial problem

[illusory]

Hello, I'm working through DT's Walk cycle tutorial. On the video 'Finishing the Contact Positions', he is copying the keyed parameters from the first frame to frame 41 (last frame) using the f-curves. After copy/pasting all the changed parameters, frame 1 and 41 are supposed to be the same. Ok, that works. Then he says, and if you scrub, see, there is no popping. Well, what if there IS POPPING?? There was movement of the knees as i scrubbed, they were not motionless like his result.

I have used exactly the same parameters he did, and copied exactly the same way. However, I did notice that the spline curves in the animation editor were curved slightly differently on his than mine. Shouldn't matter however, since you end up with a flat line when you copy the keys from 1st to last.

The only way I could get the knees to stop moving was to go and copy ALL the character key set frames from frame one to 41. I assume this is not a good method or he would have just done so, as it is a lot easier. And this created another problem on my animation. It locked the right knee straight. Now any attempt to adjust the right foot results in the knee bending backward.

Does this have to do with different version numbers of XSI? Looks like the video is from 6, where I have 7.01. I did have the auto curve option selected in preferences, as he suggested, but there were a few more options there not present in his version.

Any solutions to the knee movement problem i described?

thanks

Thanks, but where would I add an extra key frame, since this is a walk cycle? Does that mean that keying the middle parts of the walk cycle will smooth it out?

Thanks for your help

Sorry to hear you're running into some trouble. If your knee controls move as you scrub the animation, all you should need to do is copy the knee value you'd like to keep, whether it be on the last frame or first, and paste it to whichever frame would need the key to prevent the sliding from occurring. Your software version shouldn't matter as long as you can copy and paste keys the same way it's shown in the video.

Also, in regards to your last question, "Does that mean that keying the middle parts of the walk cycle will smooth it out", cycle animations, work the same way as any animation, e.g., you'll need to set keys wherever they need to be set in order for the animation to look right. At times, you may need to set a key on every frame if that means that it's going to improve your end result. Animating the midpoints of the cycle helps us to get to that end result faster.

Hope this helps!
