Calve and foot detail of robot. The ankle area is actually quite simplified. It's part of the shin and calve, as you'd see in the video of the character in rotation. I textured the area and had drawn in or painted what would seem to be mechanical elements such as struts, actuators, or beams that would presumably be associated with locating and supporting joined mechanical parts. It was more economical not to model these parts individually, and just put an illusion here and imply the mechanics in a painted UV texture. From far away, it appears just about right. Of course, close up, there's something odd, but I'd planned to capture the robot in action from farther away wide shots, or in medium to close up from the waist up.
