Mirroring Cartoon Mouth Rig?


(Yukari) #1

Say I had a model with a mouth that changes sides on the character’s face. Is there any way to mirror just the mouth in animation or rigging? This is also not a UV image.

Could we see a screenshot?

Oh, I can attach the whole file. :sunglasses:
Here it is.

Hmmm… I guess you could give the muzzle it’s own bone, and mirror it when the camera moves to the other side. This will work fine unless your using motion-blur. You could have two alternate muzzles, and maybe a third with the mouth in the middle used for tweening, and you can turn on and off whether these objects render, and attach that to a driver. You could also re-build the muzzle with the mouth in the middle, and then stretch the mouth to the side using a bone or a shapekey.

Hm, okay, I’ll try that!

Hmm… I’m still having a bit of trouble with it… I also tried mirroring the entire model and then keyframing it both flipped and not flipped, but it stayed mirrored…

The muzzle is attached to it’s own bone… when the camera moves to the other side the muzzle bone scales to -1 along local (whatever will mirror it)

Yes, but how can I keyframe it when it’s mirrored? I tried scaling but then the mesh stayed mirrored.

Muzzle.blend (1.1 MB)

You have to scale just along X by -1. Select bone and press S, X, -, 1, Enter.

Awesome! It finally works!!! Now all I still have a question about is how to flip the muzzle as if it were on the x axis when the model is not lined up with it.

I assume that this bone is going to be parented to the head bone.

You can always mirror along LOCAL y, no matter the angle of the head.
