Here I go with another one. :)

So here's what I'm trying to do. I have a model from a modeller that he's built in Zbrush and Lightwave. It's around 110k polys. I'm bringing it into Maya to animate. He's been kind enough to build a set of models to construct blendshapes as well. However, they are all LEFT sided models (ie left_eye_closed, etc) as I thought it would be a simple operation to just do a duplicate of the mesh, and scale the duplicate -1 on the x-axis. Turns out the model _looks_ like it's been flipped, but the vertices retain the original order numbers....meaning when I create a blendshape out of them, the left_eye_closed that I duplicated and scaled to make a right_eye_closed, creates a left_eye_closed blendshape. Guess it all is based on those vertice numbers.

Anyhow, I've tried a number of mel scripts from mirrorBlendhshape to Keegan's flipshape, with no success. All of them appear to be trying, but I bail on them after 2-3 hours of no apparent success. I guessing this is related to the high poly count, but who knows....

Can anyone help? :)

To use scripts for flipping blendshapes you need an absolute symetric model. I tried different scripts and fount this one to work quite well:

It also tests symetri. See the last post in the thread for some guidelines.

Hope this helps :)

if the model is non symetric you may have to delete one side and duplicate it..of course this will probably break your current blendshapes...
