M2.5: ShaderMaterial + texture resolution + fog; multi-skeleton verified
- m2_material: Metin2-style ShaderMaterial. blend_mix shader (opaque /
alpha-blend / alpha-test-cutout via `mode` uniform) + blend_add shader
(additive glow). modulate(tex, COORD) * COLOR, diffuse_lambert.
- Metin2Model: material_mode prop ("metin2" ShaderMaterial | "standard");
_resolve_texture does filename-convention + case-insensitive dir scan of
*.dds (face/hair keyword slots, stem match, fallback); set_surface_texture
override; guess_blend heuristic (hair->cutout, cape->alpha, effect->add).
Texture cache. Fixed opaque path to NOT alpha-discard (was hiding bodies).
- harness: AABB-based camera framing, engine depth fog (MTGODOT_FOG=1),
MTGODOT_ANIM_T fixed-pose capture (needs explicit anim reload first),
MTGODOT_AUTOSHOT batch screenshot.
Verified: warrior 5/5 surfaces textured under the shader (t=9 dance pose,
lit, fogged). assassin 17/17 textured via dir scan. shaman_lord (gr2 v7)
renders. Screenshots test/golden/m25-*.png, m2c-t*.png.
Gap (M2.5 gate not closed): libgr2 POD API exposes no material/texture-name/
blend data, so multi-slot -> texture/blend mapping is heuristic only. Needs
a libgr2 material API (gr2_material.cpp walking the type tree) — same gap as
xrender-poc M1 T5. Documented in docs/GODOT-POC-PLAN.md §M2.5 T2.5.6.

M1+M2: gr2 -> Skeleton3D/ArrayMesh/Skin + libgr2-driven animation
- gr2_bridge: gr2 Mat4 (row-major) -> Godot Transform3D (4x4 transpose);
build_skeleton (rest from local_transform, initial_placement folded into
roots), build_skin (bind i -> bone i, pose = inverse_world), build_mesh
(surface per gr2 mesh, ARRAY_BONES = skeleton idx via bone_bindings,
rigid meshes bound to bone_bindings[0]).
- dxt: DDS DXT1/3/5 decoder ported from xrender-poc.
- Metin2Model: load_gr2 -> Skeleton3D + MeshInstance3D + StandardMaterial3D
(runtime DDS albedo, face/body split by surface name). Z-up cm -> Y-up m
conversion on the node transform (unit_scale, flip_z, flip_winding props).
- Metin2AnimPlayer: _process samples a (separate) anim .gr2 with
gr2::sample_pose(model.skeleton, anim, t) -> set_bone_global_pose per bone;
Godot GPU-skins via skin_matrix = global_pose(i) * bind_pose(i) == gr2
deformer matrix. selfcheck() NaN-scans all anims.
Verified: warrior_cheongrin renders (75 bones, 5 surfaces, 3324 verts,
textured, upright). dance01 (dur 28.3s, 74 tracks) plays, 0 NaN over 25
samples, distinct poses at t=2/9/16/23. Screenshots in test/golden/.
