Blend shape slide problem.

Hi Guys ,

I import two head models and create a blendshape between them. But when I move the slider the target head slides on top of the blend shape geometry. How do I make it so the head stays still when being deformed by the blendshape?

And i have the origin set to local. still have the same problem.


thanks in advance.

it is mostlikely that you froze the transforms on the blendShape mesh.... the deformer needs some offset values in the transform node to offset the slide...

easy to fix:
move the center pivot on the blendshapes to an easyly i dentifiable vtx... ie top of right ear or tip of nose.... by hitting insert and holding v to point snap the piv there.... the point should also be one that hasn't been moved on the blendshape

next move the blendshape back on top of the original by snapping it (center piv should be on the top of ear in this case..)
to the same vtx on the target mesh... top of the ear...
freeze the transforms of both meshes and reapply the blend shape....

that should do it

First of all, thank you for your advice. My headache finished...uff
I was doing my facial animation with maya 4.5 and i had this terrible problem with slider...So i decided to make a test with maya 5.o ple and it worked very very well.

But the only problem now is the faces not symetrical. When i do de blend shape the vertices of the target face go crazy...Wooah...it is like an explosion....So i continue with my dilema...aarrghh
is there any way to resolve that?
