Drifting layer within bone layer

Post by Gremlard »

Hi there! I've got a strange problem whose solution is likely right in front of my face, but I'll be danged if I can find it. I have a fully rigged character that functions well, but as soon as I translate it using the transform layer tool, the mouths switch layer is *drifting*. It's basically moving slightly further ahead of the direction that the character is translated in. You can see an example below, in which the character was translated to the right.

Translated to the right

It doesn't seem to be related to binding since the mouths move fine, as long as the character isn't translated. I've also uploaded the .anme file at https://www.mediafire.com/?fechqk46xabkyha in case it might help in any way.

Thanks for looking!

If you use the orbit tool you will see that your mouth phoneme layers are all farther forward in z-depth and even tilted a bit. The different z-depth causes parallax and that is what you are seeing.

you have the individual mouth vector layers offset in x, y and z. the "z" displacement is the one at the heart of the problem. (AI and rest also have a small layer rotation). they all have a layer x/y rotation.

what I'd do to remedy this.. in frame zero, reset the vector layer offsets and rotations to be all zeros; grab all the points in each vector and move the points to be in the right place

(oops!! cross-post - sorry Wes!)

you're welcome .. and an afterthought... I'm guessing that you might have "auto center new layers" (edit / preferences / options) set... if you'd moved the camera to zoom into the mouth area before drawing (rather than workspace move / zoom) then that could explain why they're all offset.. my own preference is to disable the auto centre option by default and use it only when needed.

I did indeed have that option enabled. That'll help immensely going forward, as I've discovered that I made the same mistake on quite a few other drawings. Thanks again!
