Animation help with foot sliding
This is probably a very simple question for an animator, but I have never really done much animation before. I am getting sliding on the inward hop. I cannot figure out what I need to do to anchor the foot between these frames so it does not move. Trying to clone the position of the toe joint from the first frame to the… -
Re: Animation help with foot sliding
Is it FK motion or are you involving IK in any way? Have you looked at any parent relations, the ankle or an IK/FK switch for example, which might affect the curves? I personally think this slide is a non-issue. If you look at the knees you can barely see the slide unless you know about it. I think the animation looks… -
Re: Animation help with foot sliding
I'm a maya user so probably not too helpful, but is there something similar to the graph editor? Where you can visually see the curve, it's likely not a straight/flat line, it can be common when animating in maya and it's very easy to fix with the graph editor. -
Re: Animation help with foot sliding
Yea the copy paste POSTURE will only copy rotational relationships between the pieces and ignores world space. Copy paste POSE, can include Position data for the COM only. If you want the feet to operate in world space you need to use planted keys. But I'm glad you got it working. If you're happy to leave it at that, cool.… -
Re: Animation help with foot sliding
Yeah I do not really notice it either, but this is a pseudo learning exercise, and I really want to know why I was able to remove the sliding on the outer hop and not the inner. This is a standard biped, which might have some IK/FK switching behind the scenes, but I am not enabling or disabling that in any way manually. If… -
Re: Animation help with foot sliding
It sounds like you need to lock the foot into world space? To do that on any rig you use the built in IK system. In biped they call it "Planted Keys", but all rigs run on the same basic 2 system principle. To lock a foot into world space... You move the time slider to the beginning of where you want to lock it down (IK… -
Re: Animation help with foot sliding
Hopefully someone else is able to shine some light on the issue. I'm a Maya user myself, I have no clue how the biped rigs work. -
Re: Animation help with foot sliding
Not really sure why it worked for me just now. I shift+cloned the movement keys of the toe joint. I am almost positive I tried that before and it did not work. Anyway, thanks everyone for the attempt to help! :-) -
Re: Animation help with foot sliding
Yep, there is a curve editor, and that does not seem to help me. -
Re: Animation help with foot sliding
The problem with the copy/paste system is that it only copied and pasted the rotation of the toe, not it's position in world space. If I copied the entire leg chain, it sort of worked, but because the biped01 node was so much higher in world space, the leg could not "reach" that far down. The way I got it to work finally…
