nx_nxa_pose.nx

nx_nxa_pose.nx -- POSE section compiler: freezes ANIM channel-2 keyframes into the NXA pose library (spec: knowledge/nxa_format_spec.md POSE). A pose entry is one frozen channel-2 keyframe per joint -- [joint][qx qy qz qw q12][dtx dty dtz mm], world-delta about bind, root horizontal motion removed -- so a player applies it with the exact LBS the ANIM path already proves (M x = D(x-b)+b+dt), no FK reconstruction (which would re-introduce the dead-chain-adoption shard class: adopted joints' dt is donor-relative, not parent-relative). freeze picks its frame BY MEASUREMENT when t=-1: the sample minimizing horizontal foot separation (feet passing = legs together = reads as standing), never by taste. usage: nx_nxa_pose freeze <in.nxa> <out.nxa> <pose_id> <t_ms|-1> nx_nxa_pose list <in.nxa> rc: 0 ok, 2 usage, 4 missing SKEL/ANIM/tracks, 5 corrupt, 6 future-version, 9 io license_tier: ORIGINAL
