The stride shot regressed twice for two different reasons, and only the second was the clip. The walk cycle was authored on a sine, which is zero at both the start and the middle of the cycle - exactly the two frames where the legs pass together - so a deterministic capture at any phase near those frames read as a still. The probe proved it: frames 0 and 15 carried identical hip rotations while 7 and 22 were the stride. The cycle now starts at maximum stride (cosine). Length, amplitudes, keys and loop are unchanged; only the phase moved. demo-third-person-walk is back as shot 8 and shows a genuine stride with the curled hands from 0.2.1. 8/8 shots verify.
