Kojima has been busy doing an experiment on 3D capture, as he wrote himself. He posted some photos on his Twitter showing full body capture by means of a colorful device, some including military equipment.
Kojima pointed out that the last photo was meant for texturing.
Whether these are just tests or actually will be used in a game remains to be seen. Likely it has to do with the FOX Engine, but Kojima didn’t specify.
