Shaking ob body by walking animation

I have made a animation of walk. It works good but I can see that sometimes it gets a shaking of the body. It seems happened that when floor is not level. Why?

Any help would be greatly appreciated.

did you upload at priority4? with a lower priority, sometimes the default walk and your walk will kinda fight each other on uneven surfaces....??

Yes, I did upload at priority 4. I thing, but I not sure, that is possible problems:
- problem with animation overrider ZHAO but i am not sure because I did several animations as run, walk and always works fine when I repair some part of body like hip etc
- maybe is some parts of body wrong but animation works fine in some moments
- It seems that it has 3 different periods: one is when it works fine, second is when put the hands on the strange positon, third is when it starts to shake. I notice that it shakes also when it comes on unlevel surface

Can I get the Animation overrider in Second Life beside ZHAO which is free.

Hi!! i experienced the same problem when i made my first AO. I uploaded the animations millions time and i got really exhausted seeing that i was not getting any result. Then i thought to possible interferences between the built in animation and the overriding one. hence the enlightenment!! what if i would define an imperceptible movement for ALL the body parts which i thought to be not needed to move? i'm referring to hips height from ground and the collar sections mostly. Also setting the hands in a different position than the default one is helpful. But, more generally speaking, all the bodyparts which we are not going to move contribute to the bad behaviour you described. So just a minimal movement like +/- 0.1 than the initial value would work fine to tell SL that the default animation must not interfere. Hope to have been useful=)

I don't know why animation overriders don't check and stop the "walk" animation on a regular basis. What's happening is you're walking over uneven ground, and step down over a ledge or slope large enough to trigger he default walk, but not for long enough for the AO to have noticed that your animation state had changed.

double check, Jano, that you have moved your abdomen and chest joints away from "0" in the second frame... other than that, it is a common problem. You could set the AO timer for smaller intervals, but that is no guarantee either as it can only check the animation state as often as the server will allow it to
