Networked client on the existing Godot 4.7 + libgr2 renderer:
- net: m2dev wire protocol (libsodium KX + XChaCha20), auth/select/game
phases, EntityStore world model, ~all GC/CG headers. char create/delete,
private shop / mall / cube, SHOP_GC_START_EX, guild, party (+ CG_PARTY_SET_STATE),
quests, dragon soul, refine, safebox, exchange.
- UI: in-game windows migrated 1:1 from the reference uiscript/root .py —
char status (/stat), inventory+equipment, select-item ([SELECT_ITEM] quest
token), system-option + game-option + ESC system menu, private-shop 39-grid,
party info board, shop tabs, atlas, minimap, quickbar, chat, …
- EterGrnLib polish: GR2 material blend/two-sided, LOD crossfade, motion-event
dispatch, contact shadow, ray-AABB picking, weapon grip pre-transform.
Portable asset IO (A1) — all extension/libgr2/formats/mtproto reads routed
through godot::FileAccess (res:// PCK works on iOS/Android); standalone-lib
*_path() kept for the non-Godot CTests. AssetResolver + PropertyRegistry
switched to a baked index (bake_asset_index.gd) instead of std::filesystem.
Mobile builds: build-{android,ios}.sh, export-android.sh, pack-assets.sh,
gen-debug-keystore.sh. Assets ship as a zip mounted at runtime by
project/asset_pack.gd (adb push now; HTTP download is a drop-in later).
ctest 10/10, 34 GDScript suites, macOS/iOS/Android all build.

reference/ — archived from xrender-poc
These docs come from xrender-poc, the bgfx-based rendering POC that was
retired on 2026-08-29 in favour of the Godot route (this repo). See
../MIDREVIEW.md for the decision.
They are kept because the reverse-engineering knowledge is route-independent and still authoritative:
| file | what's still useful |
|---|---|
steps/M0-gr2-reader.md |
the entire .gr2 v6/v7 format breakdown that libgr2 implements — header, sections, Oodle1, self-describing type tree, granny_transform, OldCurveType B-splines, the "明确不做" table. libgr2 is vendored here now (../../libgr2). |
steps/00-oracle.md |
how the Wine + MinGW Granny oracle works — the ground truth for libgr2 numeric verification. Oracle harness vendored at ../../oracle/. |
steps/M1-static-render.md |
material-binding chain (granny_material → .Maps[].Map → granny_texture.FromFileName), DDS/DXT decode, the bgfx-era gotchas. The material logic maps 1:1 onto m2_material.cpp here. |
steps/M2-anim-skinning.md |
CPU LBS formula, sample_pose retarget-by-bone-name, the Granny normal-transform (plain 3×3, no inverse-transpose) — same math the GDExtension uses. Numeric gates vs Granny (≤6.5e-5). |
steps/M3-mobile.md |
iOS/Android notes from the bgfx shells — historical; Godot handles platform now. |
steps/M4-realistic-load.md |
eterpack / full-load plan — deferred in both routes. |
PLAN.md |
the bgfx-route master plan. §01 (go/no-go criteria, "工程性延期 vs 方案性死路"), §05 (format findings), §07 (visual-diff layering) are still the shared vocabulary. |
DEMO-PLAN.md |
bgfx RHI demo design record. Mostly superseded; kept for the shader/material-stage analysis. |
Relative paths inside these files (../libgr2, oracle/, test/golden/…,
engine/…, app/…) refer to the old xrender-poc layout. The mapping:
