The multi-shader attribute scheme is used in the downgrading scheme of the mixed animation, but the GPU has a limit on the number of attributes. The current implementation is relatively rigid and only supports 4 blendShape blends. We need to dynamically detect GPU capabilities to support more blendShape numbers.
