Blend Shape on Wrap Deformer SLOW!

[mark77]

I have a wrap deformed character applied to a skeleton, with blend shapes for the face. And I can't believe how slow my blend shape sliders are. I'm waiting 10 seconds for my eyebrow to raise. On a 2,000 poly mesh.

I went through the manual, and only found the Max Distance setting of the Wrap Deformer, to change the speed of the "deformation of my object." All it did was deform my character much quicker...but my blend shape speed is the same.
Any help or Suggestions would be great.
Thanks

I'm not sure how to change your blendshapes prob...but if your geometry is that heavy, you can opt to set up the face with clusters and attributes for their deformations.

A foolish consistency is the hobgoblin of little minds.

Wrap deformers are slow. But I guess you're not wrapping the blend shapes (creating blend shapes on a low res model, and wrapping a high res model to that).
So what you could do is animate the blend shapes on another model. Create a copy of the head with blend shapes, and animate that. There are several ways you could connect this animation up to your wrapped character. I.e. connect the sliders you use on the seperate head to the shapes on the wrapped head, use the seperate head as a single blend shape on the wrapped one, perhaps connect the outMesh on one to the inMesh on the wrapped one (not sure this would work).

Anyway, that might solve your problem.

Also if your head is a seperate model from the body. It might be a good idea, not to wrap the head, but just skin it the old fashion way. Heads are fast an easy to skin, as it's more or less only the neck that deforms.
