Thanks Guys this is very helpful. Thanks for the explanation and screenshots Sandy.
The major difference between your approach and mine was that you use Linear Interpolate. And I was multiplying the shape vectors by the scalar that was returned from the controller position. I wonder if that could be part of the cause of my rigs slowness On Wed, Apr 24, 2013 at 4:45 PM, Peter Agg <peter....@googlemail.com> wrote: > I'd also avoid doing things with weightmaps as much as possible - far > better to do all those calculations outside the rig and then freezing the > shape on export.
