2V2-e.2: Godot consumer of the 3D draw commands, offline screenshot
python_3d_surface.gd turns RenderGame's recorded draws into meshes under a camera read back from SetPerspective; textures come from the 40250 packs. GetFarClip and the CMapManager ctor ported verbatim. Until the environment is ported, lit draws with no light/ambient are shown unshaded (stand-in). script/python_game_render_test.sh runs system.py login -> select -> game against port_fake_login_server (or --live via MT_LIVE_*) and screenshots.

# python_game_render_test — 2V2-e：Godot 里跑 40250 的 system.py，按 port_login_flow_test 的同一条路径
|
||||
# 登录 → 选人 → 进游戏，把 RenderGame 的绘制命令（python_3d_surface.gd）画出来并截图。
|
||||
#
|
||||
# godot --path project --script res://python_game_render_test.gd
|
||||
#
|
||||
# 服务器与账号只从环境变量读（MT_LIVE_HOST / MT_LIVE_LOGIN / MT_LIVE_PASSWORD，可选 MT_LIVE_AUTH_PORT
|
||||
# 11000、MT_LIVE_GAME_PORT 13000、MT_LIVE_SLOT 0）；Python 侧也用 os.environ 取，不进源码文本。
|
||||
# 离线由 script/python_game_render_test.sh 起 port_fake_login_server 并把这些变量指向它。
|
||||
# 截图与 report.json 写到 MT_RENDER_OUTPUT（默认 build/rendering/python-game-<时间>）。
