本文是关于起源 2013 引擎分支. 关于 Source SDK Base 2013 的信息, 见 Source SDK Base 2013.

起源2013引擎分支（又称 SteamPipe 分支）是橙盒引擎分支分支的最终迭代。Valve 于 2013 年推出该分支，旨在用求生之路引擎分支引擎分支中引入的 VPK(en) 格式取代过时的 GCF(en) 文件格式。
此次更新带来了内容挂载方式的重大变革，所有使用起源2009和起源多人分支分支的 Valve 游戏都升级到了该分支。包括半衰期：起源半衰期死亡竞赛：起源和半衰期2：失落的海岸线从起源2006引擎分支升级为该引擎分支。
新增的custom文件夹简化了模组制作流程，为每个起源游戏单独设置了挂载路径。

尽管 SteamPipe 因简化了起源引擎挂载内容的方式和公开未发布的（2025年2月19日）军团要塞2代码而备受赞誉，但也导致大量模组失效，加剧了起源2009分支既有的问题。由于部分起源2013 游戏（除、等外）包含重复的《半条命2》基础内容，导致存储空间需求增加，同时为半衰期：起源引入了更多bug(en)。该分支亦未具备求生之路引擎分支后续引擎分支的多数特性。不过经过持续优化，修复了橙盒分支遗留的诸多漏洞（如《半条命2》中运输机货舱机枪失效、NPC眨眼动画缺失等问题），现已成为现代非商业化引擎模组使用的主力分支。

子分支 (SP/MP)

起源2013 分为两个子分支，起源2013 单人分支和起源2013 多人分支，它们分别取代了起源2009 和起源多人分支分支。两个子分支的代码库相互独立，但功能基本互通。多人模式分支包含单人模式分支不具备的部分特性。
自 2022 年起，军团要塞2 使用的起源2013 多人分支分支经过引擎更新后，形成了一个不兼容的新版本，即军团要塞2分支（独有页面）。截至2025年2月19日，所有剩余的第一方 Source 2013 多人模式游戏(, , , ) 和 SDK Base 2013 - MP 均已升级至该分支，完全取代了旧版起源2013 多人分支分支（也叫 Source 2013 Multiplayer Legacy）。
而起源2013 单人分支分支虽引入了新功能（如《半条命2》的 Steam Deck 更新以及20周年纪念所更新的特性），基于旧版SDK 2013 SP代码构建的模组和工具仍可兼容。但若使用旧版SDK 2013 SP代码的模组运行于新版SDK 2013 SP代码构建的游戏上，将无法完整支持新功能（如Steam输入、径向雾效、经典粒子系统、HUD 宽高比适配等）或可能运行异常。目前 Valve 尚未发布更新后的 Source SDK Base 2013 SP 源代码。
截至 2025 年，Valve 和第三方开发者仍在积极维护该分支下的所有游戏。但Valve仅维护起源2013 单人分支分支，因为起源2013 多人分支游戏已被军团要塞2分支取代。

提示:尽管名称不同，但这两个分支都可以用于单人游戏。
由于多人游戏分支的附加功能所带来的好处（静态道具 lightmaps 、 BSP 压缩、环境光立方每可见性、小幅度代码更新），只有在使用Mapbase等基础mod或制作不修改游戏代码的单人mod时，才应使用单人分支。

TF2 分支的部分改动（不限于网络模块）会导致单人模式崩溃，例如：生成携带 Strider 货箱类型的运输机会导致游戏崩溃；尝试加载任何maxplayers 1（单人模式）地图也会导致崩溃（参见

的图形压力测试）。

特性

半衰期2, introduced in 2022.

待完善: 待将部分转化为翻译链接

New since the 起源2009 and 起源多人分支 engine branches are:

VPK(en)文件与{{path|custom}（自定义）文件夹: 首次在求生之路引擎分支中引入，后扩展至起源2013，取代了旧的GCF(en)格式。Source 2013 支持从 custom 文件夹直接读取文件，简化了模组安装流程（无需覆盖原版文件）。部分Source 2013游戏（如黑山）需手动创建custom文件夹。Source 2013 使用 VPK 版本 2。
Linux、 Android、跨平台支持: 引擎现可运行于Linux、Android（Nvidia Shield设备）、任天堂任天堂Switch等平台。但非官方游戏对这些系统的支持可能不稳定。
静态道具光照贴图 (仅存在于之中)(也存在于之中) （单人分支未完全支持） 待完善: 按照军团要塞2分支页面更新要求，将only换为since: Static props without bump maps can now use lightmaps (albeit with limitations).
Per-texel color tint masking for models: $blendtintbybasealpha is ported from the 求生之路引擎分支. 起源2013 includes an exclusive additional parameter, $blendtintcoloroverbase.
BSP compression (仅存在于之中)(也存在于之中): BSP maps and packed files can be losslessly compressed on both server and client.
Direct3D 9Ex / Windows Aero DirectX Extensions (也存在于之中): Improve performance depending on GPU hardware and drivers. Additionally, running those games on Windows 10/11 will automatically enable fullscreen optimization, which will allow quicker Alt + Tab ⇆.; 错误:Cannot be disabled even with mat_disable_d3d9ex 0 (or Windows Aero DirectX Extensions set to "Disabled"). Applications such as Special K still reports the game using D3D9Ex (through FlipEx).
To actually disable D3D9Ex, you will need to use -nod3d9ex. (tested in： )
Raw mouse input: Directly taking unchanged data from mouse drivers before it goes through operating system enhancements, meaning that mouse input will be exactly 1 to 1.

Steam Deck 更新

Gamepad UI (仅存在于之中): Introduced in 2022, Gamepad UI is a modern controller-oriented UI designed for consoles and handhelds like Steam Deck. With the new Gamepad UI, it was more scalable across any resolution (including 4K and higher), unlike the regular VGUI at the time (which, the higher the resolution, the text and UI will become smaller). VGUI (except on consoles /), are harder to navigate, and sometime cannot be navigate with a controller. This UI can be also enabled manually by using -gamepadui command line argument, or running the game when Steam Big Picture mode is active.
Enabling Gamepad UI will also enable Vulkan renderer. If your GPU doesn't support Vulkan or if you don't want to enable Vulkan, uses -dx9 alongside the -gamepadui command.
Vulkan renderer (仅存在于之中)(仅存在于之中)(也存在于之中): A low-overhead, cross-platform graphics API, successor to OpenGL.; First introduced in 2022 with 半衰期2 and 传送门. Portal with RTX also uses Vulkan as part of the RTX Remix runtime. Using DXVK, a library used to translate Direct3D calls to Vulkan. This is disabled by default, but can be enabled in supported games by passing -vulkan into the game's launch options.

"半条命2" 20周年更新

注意:These features are also available in 半衰期：起源 (or mods running on 半衰期2 base instead of SDK 2013) after 半衰期2's 20th Anniversary update.

VGUI High DPI support (也存在于之中): VGUI are now properly scalable on higher resolutions such as 4K (3840x2160).
Bicubic lightmap filtering (也存在于之中): Introduced in 2024, bicubic filtering is used on lightmaps when r_lightmap_bicubic is enabled, smoothing out aliasing caused by the lower resolution of lightmaps. It can be also enabled by setting the Shader detail to "Very High".
Radial fog (也存在于之中): Unlike planar-based fog, radial fog does not strengthen or weaken the apparent amount of fog in a particular spot when you rotate the camera.; You can either use radial fog or planar-based fog by changing env_fog_controller "Use Radial Fog (fogRadial)" KeyValues.
Continue music playback after loading levels (也存在于之中): Introduced in HL2's November 26, 2024 Update, music will continue to play after the next level is loaded, instead of stopping completely like in previous versions. Can be toggled using save_transition_music console command.

军团要塞2分支

军团要塞2分支现拥有属于自己的页面。

Removed features

Patching levels with lump files (仅存在于之中): Patching levels using lump files (to change the map entities without recompiling the map) is no longer possible in MP branch, and possibly 军团要塞2分支^[证实].
Built-in VR headset support (SteamVR, Oculus VR, etc...) (仅存在于之中): The option to enable VR headset support in Video Options, originally introduced with the release of Source 2013, was removed in later updates of 半衰期2 (since 2022 Steam Deck update). Instead, player can install mods such as Half-Life 2 VR Mod to play in VR.

可见性

Source 2013 多人游戏和单人游戏分支的游戏代码都包含在 Valve 的 Source SDK 2013 repository 存储库。

警告:By default, some of the gamecode for the SDK 2013 are massively out of date, and does not contain many updates and bug fixes (such as Dropship(en) gun fix) that was introduced in 半衰期2 and 传送门 (since the new Steam Deck update) respectively, nor the "upcoming" builds on Steam, along with the rest of 起源2013 games. Furthermore, the MP builds (on Steam) are more up to date than the SP builds.

第三方使用 Source 2013 分支

The following games use neither nor , but rather use custom (heavily modified) branches forked earlier versions from both Source 2013 branches, with newer features added on. As such, they may or may not include all features from newer first-party versions of Source 2013, such as LZMA-compressed BSPs or lightmapped MDLs(en).

黑山 (branch also known as "Xengine")
Garry's Mod (which also support some features from Alien Swarm, Portal 2 engine branch and onwards, such as partial VTF 7.5 support). Also have 64-bit executable.
