I\'m currently trying to export an animated blender model to three.js using the exporter of three.js (github.com/mrdoob/three.js/tree/dev/utils/exporters/blender/2.66/script
I had an issue where calling THREE.GeometryUtils.center(geometryWithBones) on a the newly imported geometry would make all the skinning look very strange. Getting rid of that fixed things.
