- 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.
