Source 2004
October 27, 2005 (
, v2)
Source 2004 is the original build of the Source engine that Half-Life 2, Half-Life: Source and Counter-Strike: Source shipped with, then subsequently updated with the release of Half-Life 2: Lost Coast (and Day of Defeat: Source), adding some features which would become standard with Source 2006. The Source 2004 engine was succeeded by the Source 2006 engine branch with the release of Half-Life 2: Episode One.
No current Valve titles hosted on Steam use this particular engine branch, as it is outdated.
It was distributed in source engine.gcf.
Vampire: The Masquerade – Bloodlines still runs on a custom version of the engine which is more similar to the engine used in the Half-Life 2 leak (unofficially referred to as Source 2003). However, it uses a proprietary texture format, Python for scripting, BSP version 17, and supports Bink videos.
SiN Episodes likely runs on modified Half-Life 2: Lost Coast version of Source 2004, which contains few commands related to the HDR Rendering which was non-functional ("mat_hdr_level"), aside from that it also stripped BSP 20 support from Lost Coast.
The engine versions for this branch are build 2106 up to 2497 (Protocol 5-7). The second version of Source 2004 (introduced with Lost Coast, adding HDR and other new features), started with build 2547 until 2707 (Protocol 7).[1]
Features
- Support for
Original Xbox game console - Steam Friends & Parlor Games menu (removed in later version of Source 2006 in 2009)
- Shader Model 2.0 only
- Anti-aliasing
- Up to 6x MSAA. 8x MSAA unofficially supported through mat_antialias 8, but will reset to 4X on next launch. MSAA 8X can be also forced through GPU drivers control panel.
- 6x MSAA does not work on modern graphics card. Only 4x works.
- DirectX 9.0
- Uses Direct3D 9.0, with support for these hardware levels:
- DirectX 6.0 (dxlevel 60) level (not officially supported, but works)
- DirectX 7.0 (dxlevel 70) level
- DirectX 8.0 (dxlevel 80) level
- DirectX 8.1 (dxlevel 81) level
- DirectX 9.0 (dxlevel 90) level
- Inputs
- Support DirectInput controller only
Since Lost Coast engine update
- High Dynamic Range rendering[2] (DX9 SM2)
- A simulation of brightness values outside computer monitors' actual range, and of aperture adjustment. Not to be confused with HDR display output.
- While being attributed to Source 2006, this feature was first introduced with Half-Life 2: Lost Coast (which runs on updated version of Source 2004).[2][3] Half-Life 2 was also upgraded to Lost Coast version of Source 2004, but all Half-Life 2 maps are not HDR-compiled by default, leaving HDR feature unused. SiN Episodes also runs on this version and feature mat_hdr_level console command, but support for HDR was stripped in code which leaves it non-functional.
- Direct3D 9 - Shader Model 3 (DirectX 9.0+ feature level/dxlevel 95)
- Unlocks greatly improved shader performance.
- Commentary System
- Allows DVD-like director's commentary to be embedded inside levels. Commentary System was used in Half-Life 2: Lost Coast.
Removed features (post-launch)
- 64-bit binaries
- In December 2005,
Half-Life 2 and Half-Life 2: Lost Coast was updated to add 64-bit support, allowing it to access more than 2GB (4GB with LAA) of RAM, and increase performance slightly. However it was later discontinued and removed due to its instability on some systems. 64-bit support was later reintroduced with Counter-Strike: Global Offensive (on Mac/Linux), and later Team Fortress 2 branch, without any technical issues. Titanfall branch also have 64-bit binaries.
Availability
The source code for this branch is no longer officially available. All Valve games that run on Source 2004 are now currently using Source 2013 Singleplayer or the Team Fortress 2 branch (formerly Source 2013 Multiplayer).
An archive of the 2004 SDK is available on GitHub.
