about

nx_nxa_anim.nx -- ANIMATION IMPORTER v2: extracts the FBX's authored animation and BAKES it to the NXA's normative delta-LBS convention. v1 wrote raw Lcl-space Euler quats (channel 1) which are NOT drivable without the FBX local hierarchy (pre-rotations, parent chain); v2 evaluates full integer FK per 30Hz sample -- local = PreRotation x LclRotation(t) chained down the joint parents -- and emits per-joint WORLD-SPACE deltas about the bind pose (channel 2, packed 2-word keys), the exact form the LBS viewer consumes: M x = D(x-b)+b+dt. SELF-VALIDATING: the static FK must reproduce the SKEL bind translations (TransformLink ground truth) or the tool REFUSES (exit 7) -- pre-rotation/hierarchy math is proven against data already trusted, never assumed. usage: nx_nxa_anim <in.fbx> <in.nxa5> <out.nxa> rc: 0 ok, 2 usage, 3 fbx unreadable, 4 no animation, 5 in.nxa bad, 7 rig-mismatch, 9 io license_tier: ORIGINAL
