Committed to this self-hosted private repo so a clone builds on any machine
without a separate asset sync. Copyrighted Ymir art — do not publish or

Rendering fixes (real):
- m2_material shaders: cull_disabled -> cull_back (inside-of-mesh faces were
z-winning and darkening/hiding the head under the ShaderMaterial path).
- drop `* COLOR` from the shader (meshes carry no ARRAY_COLOR).
Animation: convert gr2 global poses to Godot *local* bone poses and set via
set_bone_pose (was set_bone_global_pose). MTGODOT_VERIFY=1 confirms
get_bone_global_pose(i) == conv(world[i]) for all 75 bones (<=2.6e-5).
Head/upper-armor collapse on dance_1 is NOT a Godot-route bug:
- reproduced identically in xrender-poc's bgfx demo at the same anim/t
- reproduced by the new MTGODOT_CPUSKIN=1 reference path (same LBS math as
xrender's validated skin_mesh)
- `general/wait` / `run` render correctly in all three
=> upstream libgr2 Curve::eval (degree-2 quaternion B-spline) vs Granny.
Demo default animation switched to general/wait; documented in MIDREVIEW §4
and README. Debug scaffolding gated behind MTGODOT_VERIFY / MTGODOT_CPUSKIN.

- docs/MIDREVIEW.md: what M0'-M2.5 proved, bridge-layer LOC (~1100),
key technical conclusions (4x4 transpose, animation method B, no
handedness flip needed), remaining risks, recommendation = enter Phase 2
with a 3-item wrap-up (compare.py, dump_materials oracle, refocused perf).
- harness MTGODOT_STRESS=N: grid of N animated warriors, vsync off, dumps
test/godot-macos-stress.json. Frame times are throttle-capped in a
background window (~30fps to 50 chars, 52ms at 100); the reliable signals
are build cost ~165ms/char and the 100-char breakout.

- Metin2Model stores gr2::dump_materials() and can resolve surface textures
via tri_groups[0].material_index -> material.diffuse_texture basename,
gated behind use_gr2_materials (default off): the mapping is unverified and
currently regresses warrior (body surfaces pick the face texture), so the
filename-convention + dir-scan path stays the default.
- Property + setter for use_gr2_materials so it can be A/B'd once a Granny
oracle exists. Logged: "gr2 materials: N (M with diffuse name)".
warrior/assassin/shaman render unchanged from the heuristic path.
docs/GODOT-POC-PLAN.md §M2.5 T2.5.6 gap list already covers the open item.

- extension/: godot-cpp submodule (master, API 4.7), Metin2Model node
registered, links xrender-poc/libgr2 via sibling-dir reference.
- project/: Godot 4.7 project — orbit camera + DirectionalLight3D (shadows)
+ WorldEnvironment/procedural sky + placeholder cube; main.gd probes the
extension and can run libgr2 on a real .gr2 (MTGODOT_PROBE_GR2).
- build.sh one-shot build into project/bin/.
- docs/GODOT-POC-PLAN.md (phased: Phase 1 macOS -> M0'/M1/M2/M2.5).
Verified on this machine:
[mtgodot] Metin2Model registered OK — libgr2 linked
probe_gr2(warrior_cheongrin.gr2) -> gr2 OK: format_version=6 sections=8
Metal Forward+ renders the scene (test/golden/m0-scaffold.png).
