Fightura

**Elbows and knees fold cleanly at any angle.**

Past a right angle the inside of a folded limb pushed each half into the other: the arm came out through its sleeve at a swimming stroke, and the sides flickered where they lay flat on each other. The inside isn't blended any more. Each half keeps its inner face flat and the two meet in a clean crease, like the corner of a picture frame, and the texture is cut off at the crease rather than squeezed into it. Nothing passes through anything at any angle Epic Fight bends a limb to, and the groove across the crook of the arm is gone.

The outside now curves round the joint at exactly the limb's thickness, so the elbow doesn't bulge and the arm doesn't narrow where it bends, and the curve is cut twice as fine so it stays round at a 137° knee.
