I did a search on this subject and didn't find anything useful. I am trying to have a character do a simple jog and keep getting this "leg spazz" (please see small animation file link) that is driving me nuts. I've tried a number of things. Has anyone seen this before? If so, what's the fix ... if there is one? Thanks!!!! _Tim

a couple thoughts on this one.... in walk designer make sure your loading the correct character file ...some have longer/shorter legs than others... may also try retiming the animation with a fewer keys...theres also a spline editor but i think retiming keys does pretty much the same thing... good luck

heyas; i've seen worse. :) did you turn off ik before you applied the walk deisgner walk? it looks a bit like the foot is confused as to where it is supposed to be targeted for it's ik. another problem is.... the walk designer isn't an exact science. you're trying to mix together several different walking animations, and sometimes information in them clashes in the most... interesting (painful? ;) ) ways. if the walk designer preview did this, try tweaking the slider settings just a hair to get rid of it.

Thanks for the input. Here are the facts: -Correct character loaded -Reset all Walk Designer sliders to defaults, then slid run up to about 37%. So no conflicting parameters. - Walk Designer Preview appears absolutely flawless (that's the frustrating part!) - Have tried retiming to no avail - I BELIEVE I turned IK OFF, but it COULD have been after the animation was created. I'll double-check on this one. Thanks.

Here's something else to check. Poser doesn't like figures that have the legs locked straight (or even almost straight) when the figure is in the default pose. Check the figure at it's default pose and see if the knees are bent slightly. If they aren't. Then I've noticed Poser gets cofused and doesn't know which way to bend the shins sometimes. ScottA

Your message is a little confusing ... to clarify, are you saying they SHOULD be bent slightly for the starting frame or they should NOT be bent? Thanks.

heyas; should be bent. i read somewhere that poser uses a slight initial bend in body parts to know which way to fold them up when you use ik. if the legs were perfectly straight, it's a 50-50 guess as to whether the knee folds forwards or backwards ;) you might also fix this by hand, timoteo. just advance forward frame by frame until you get to the jiggling frame. try deleting the keyframe for that, and perhaps the ones around it. (as i recall, using the walk designer makes every frame a keyframe.) you can adjust those frames by hand, if you have to.

Blood: I was doing that actually ... it jsut became incredibly tedious and really annoying. Basically, I just had to delete two keyframes for the right foot at each hichup and the spline took care of the rest. But still, it's a lot of hichups. Also, here is a another problem: After each complete cycle of steps (one left, one right) the figure has a slight pause (which is painfully obvious). The animation linked above just barely gives you a glimpse of this other "hichup" ... but it's there. Any thoughts on that problem as well? Thanks you all. -Tim

heyas; fix the right leg spazz and the left leg spazz, then save that sequence to the pose libraries as a multi-frame animation. save one less frame than a complete cycle. for example, if you are doing a 15 frame cycle, save frame 1-14. the reasoning for this is, the end and start frames should be identical. if you loop or string the cycle together, the two identical frames will be together, and generate a pause in your animation. remember, once you get one cycle fixed, you can save it to the pose libraries and just add it to the end of your current cycle to get more. you don't need to rely on the walk designer doing all the strides. not quite sure how this affects the positioning (i usually only do cycles standing in place), you may want to ask in the animation forum.

Yeah, that's exactly the problem ... positioning. Almost none of my animations involve things happening in place. Thanks anyway.

Here is another fix foryour jogging problem look in the "Poses" directory you will see "WalDesigner" and WalkDesingerP3 WalkDesigner has "tweaked" WD files in it. One of which is a nice run or job. The thing that causes all those quirky little things like knees bending the wrong way are one, bad or not great joint parameters, two IK is on,and/or three use limits is on or off JanP

Thanks! I'll check it out. -Tim
