well, first off, the thumbnail is just butt as this entire piece is about it as the main subject... lol :D, for the sake of science of course!
anyways, it's to show the skinning time ! learn alot about humanIK roll bone system & skinning setup for mid poly character :) !
I used a combination of ngSkinTool and several smooth skin tool plugin along with my own home-made script to aid the skinning process, which I end up quite enjoying doing actually.
The animation was done entirely using just bone and skinning so I was able to export it into UE4 and render the sequence out of it.
