Sorry I took so long to get back at you on this. Yes, the 2nd file you posted was not as badly screwed up as the 1st one, but it’s still pretty messed up. Where did you get the rig for this character???
Alright, this is what I noticed as screwed up so far: You have the deform modifier on the torso, and both feet, which is fine, but you also had them on the knees, which is not needed. You also have two curves for paths, yea, sure only one of them is being used, but the second one being there is just sloppy. So I removed all the deform modifiers in the NLA editor, after I did that, I ‘right-arrow’ to advance the frame, and the character changed in it’s scale, became smaller, not sure why.
Go ahead and remove the modifiers and the curves, and try to get your character to walk, he’s still all screwed up. So it’s not the modifiers that’s your problem, it’s the rig and how the rig was used on the mesh that is your problem.
Here’s a short rundown of what I found wrong with the rig: There is no head bone, but two neck bones, so I assume neck2, the top most bone is his head bone. It’s not aligned with your characters mesh correctly, it starts where your characters shoulder are and ends below the base of the head. It has eye target bone parented to it. The eye target bones are below his chin, no up in front of the eyes. The ‘uparm’ bones are not position to start at the shoulder, the are located in the top of the chest. There are elbow targets that are way to close to then center of the character, and I can’t anywhere find them being used were they are being used (usually such bones are ‘targets’ for a constraint) Maybe that’s why the character walks with the elbow pivoting in the wrong way. Most people’s elbows bend backwards, you character walks with his eblow bending in front of him. And the knee targets are way to close for the knees (I didn’t even look to see if they were being used).
Whew, I am gonna stop there. I gotta say, and I say it alot, this tutorial I did was the best thing ever for me…
Go thru the whole thing, i think you could learn alot,
