Blendshapes Shifting Masterhead Problem!

[lotty]

I attatched blendshapes to a rigged model head, which I have to extract from the body.
They work however the head wonders off the body and goes on top of the target blendshape.
Skin Weights are still in tact however its a fair bit away from the body.
How do i keep the head with the body but give it the blendshape targets?

either your blend is set to global set it local

Or this is about the one thing you dont normally see namely the center of your transformations matrix, and you have moved the head and frozen the results thereby moving the enter of your coordinate locale. Now unfortunately this effect cannot be easily reversed unless you happen to have a reference intact. I wish people who don't know what a transform matrix is and where the center is is would refrain from using freeze.

So move your body to 0 0 0, rotation 0 0 0 , scale 1 1 1 , shear 0 0 0.

move the heads by snapping sioome known static reference, then freeze the subhead now your free to move it to side

hmmm i have tried this and no luck, I actually think its to do with the fact it has been skinned first and then blend shapes. so I think the blendshapes are over riding the skinning?

There is a way to swap them i think I just dont remmeber the menu..?

Yes but it does not affect the shoot off, right click the arrow in icon in your status line, choose show all to reorder them. But as i said sjthe moving of body is a very very common symptom of frantic freezer syndrome.

hello, yeah rigging first and then making blendshapes isn't the right order, however there is a way.
when u create the blendshape click on the "box" go to "advance" and instead of having the blendshape being "front of the chain" causing the blendshape to override use "after". if that dosen't work test the others.
it was along time since did these sort of things but it should work.

but still the shutoff is likely to be a feature of the blend shape itself*. But yes offcours the blend shape after deform can do this yes but you don't need to recreate a blend just to move it about in the history read my post again it has instructions on how to get into the gui for reordering history, just middle drag new order.

*depends on how its injected mainly, you can put blenshape after the fact that don't shoot off, especially if you flush the inbound target shapes form history as it only holds deltas in the history, in that case the shoot off is the problem of the shapes themselves. Theres a 50% 50% chance of either of theese being right. (because we don't know other states, but still the former is more common.)
