nx_nxa_texbake_decode_t279.nx

nx_nxa_texbake_lib.nx -- ★TEXTURE LADDER rungs 2b+3+4 (debt 1786546859, successor of the TEXC format rung): (2b) REGION GROUPING: every joint classified Face|Torso|Limbs|Gens from its OWN bind anatomy (permil of the vertex z-span + laterality -- the same normalization basis nx_nxa_dyna uses, joint ladder is shorter than the mesh so the VERTEX span is the ruler). (3) ALBEDO BAKE: fills the TEXC atlas (grid g read FROM the TEXC section -- the wire format is the SSOT, two copies of one capacity are two capacities) with per-region skin albedo + a WHISPER of fine grain. Real skin is EVEN -- the coarse-blotch regression is banked (HONEST_vs_REAL_PEOPLE); grain is +-3. (4) SAMPLER VIEW: binds the baked atlas to the trimesh renderer's EXISTING per-fragment image-texture path (tm_set_image + tm_vuv + smooth=2 -- it was already there; this wires TEXC into it) and renders a lit, z-buffered, textured turntable of the asset. check-before-build: NO new rasterizer. Output atlas format == TM_IMG contract: res*res*3 u8 RGB row-major. FAIL-CLOSED: no TEXC -> refuse (run nx_nxa_texc first); counts mismatch -> refuse. Deterministic by seed. license_tier: ORIGINAL No hw writes (Rule 26).
