about

nx_skeleton_gate.nx -- gate for SKELETON + LBS SKINNING (the character-foundation rung; VAMX R3). T1 hierarchy compose: a 2-bone arm posed at known angles -> child world position matches the HAND-COMPUTED value (integer-trig tolerance) T2 skin follows the pose: a vertex rigidly bound to the forearm lands exactly at its rotated position T3 blend: a joint vertex weighted 128/128 lands midway between the two bones' rigid transforms T4 determinism: pose->skin twice, outputs byte-identical T5 PNG knowledge/nx_skeleton_arm.png: a skinned 2-bone tube STRAIGHT vs BENT 90deg -- smooth joint visible license_tier: ORIGINAL expect_exit: 0
