nx_quadruped.nx

nx_quadruped.nx -- QUADRUPED rig + walk gait + body-fill: the bestiary's ANIMALS move too (operator thesis: reuse synthetic assets "from animals to people to monsters" + give them motion). An 18-joint quadruped rig on the SAME nx_skeleton FK substrate (root barrel -> chest/head + hips/tail + 4 three-bone legs), a DIAGONAL WALK gait (FL+HR swing in phase, FR+HL antiphase -- the real quadruped walk coordination; legs point -y so a pitch(Rz) swing moves the foot along the body axis x), and quadpose_fill = the wolf body as bone-anchored ellipsoids + sphere-chain legs/tail on the CURRENT pose, rendering on the production shader like everything else. Gait parameters are data (amplitudes/period per call). license_tier: ORIGINAL
