public void SetBlendShapeWeight(int index, float value);


index The index of the BlendShape to modify. Index must be smaller than the Mesh.blendShapeCount of the Mesh attached to this Renderer.
value The weight for this BlendShape.


Sets the weight of a BlendShape for this Renderer.

The weight of a BlendShape represents how much the Mesh has been blended (or morphed) from its original shape to a target BlendShape (another Mesh containing the same topology, but with different vertex positions than the original). The BlendShape weight range includes values between the minimum and the maximum weights defined in the model.
