Blown away by this solution by Joe Alter. It looks like an alternative from getting Muscle Deformation in rigs. Looks like its a form of blendShape solution utilising deisplacement to generate key pose effects of muscles. Judging from the demo, the system looks fast. But might be alot of work setting the system up? Cant wait for the system to be release by Joe Alter.
