Installation for Source 2006 games

Hammer++ compiling an CSS map, using Source 2006 compilers.

Todo: Add a section for SiN Episodes (which runs on updated Source 2004, and also one of the Old Engine branch) and confirm if its works for that game or not.

This page show you how to get Hammer++ to work on Source 2006 games. Currently this is only tested in an old version of Counter-Strike: Source (v34) with unpacked "cstrike" files, and Source SDK 2006's sourcetest (aka Source Engine Test) with depot VPK files.

Installation

Hammer++ - Game Configurations tab

Hammer++'s - Build Programs tab

Prerequisites

Source SDK (AppID 211) - Click to Download/Run - includes Source 2006's compilers.
Hammer++ (Source 2013 Singleplayer or Source 2013 Multiplayer)
A Source 2013 game (or Source SDK Base 2013)
Older version of Half-Life 2, Counter-Strike: Source (or any Source 2006 games/Source SDK Base 2006)
Steam account with Half-Life 2, Day of Defeat: Source or Counter-Strike: Source owned
- If you are compiling maps for Counter-Strike: Source or Half-Life 2 Old Engine, you must own the game in order to compile maps for these games. This does not apply to SourceTest or any Source 2006 game/mods with AppID 215 on gameinfo.txt.
- The map compilers will refuse to run with SteamStartup() failed: Missing interface if you don't own any of these games.^[1]
Atleast 15-20GB disk space

Source SDK Base 2006 (`sourcetest`)

1. Install Hammer++ to Source 2013 (either SP or MP branch), then open Hammer++: Just drag the Hammer++ files to the Source 2013' bin folder.; When launching Hammer++, if there's a pop-up asking you to select any game, select "SourceTest"; Then go to Tools > Options > Edit > Add and name it "SourceTest (Old Engine)"

Bug:On some systems or depending how Windows was configured, Hammer++ may crash every time it tries to show the show the file dialog. See Hammer++#Caveats for a workaround.

2. Game Data Files (FGD): You can either use the Source 2013's halflife2.fgd or Source 2006's halflife2.fgd, as both have the same contents. Some games that have been updated from Source 2006 > 2009/2013 may have new entities and stuff added into the FGD which are not present in previous versions of the game/branch.

3. Game Configurations - change the following directory:

Game Executable Directory:

$SteamUserDir\Source SDK Base

Game Directory:

$SteamUserDir\Source SDK Base 2013 Singleplayer\sourcetest

You must set this to Source 2013's "sourcetest" as loading Source 2006's "sourcetest" will led to Hammer++ attempt to load old shaders, which will cause Hammer++ preview to stop working.

Hammer VMF Directory:

...\Counter-Strike Source Old Engine\Counter-strike Source\mapsrc

This is where you would save the VMF file. Can be changed to any directory you want.

Prefab Directory (optional):

...\Counter-Strike Source Old Engine\Counter-strike Source\

Like VMF, this can be changed to any directory you want.

4. Build Programs: Game executable: Point to $SteamUserDir\Source SDK Base\hl2.exe (or any Source 2006 game's hl2.exe); BSP executable: $SteamUserDir\SourceSDK\bin\ep1\bin\vbsp.exe; VIS executable: $SteamUserDir\SourceSDK\bin\ep1\bin\vvis.exe; RAD executable: $SteamUserDir\SourceSDK\bin\ep1\bin\vrad.exe; Place compiled maps: $SteamUserDir\Source SDK Base\sourcetest\maps

5. Restart Hammer++

6. Load any VMF and make sure it's works, then press F9:

Switch to "Expert...", and in the "Default" configuation.

Then, change the VBSP, VVIS and VRAD parameters from:

-game $gamedir

to

-game "...\common\Counter-Strike Source Old Engine\Counter-strike Source\cstrike"

Do the same thing for "Fast", "LDR + HDR Full Compile", and so on.

7. With the last command "$game_exe", replace the following:

Commands: $game_exe

Parameters: -dev -console -allowdebug -hijack -game $gamedir +map $file

with

Commands: "C:\Program Files (x86)\Steam\Steam.exe"

Parameters: -applaunch 215 -dev -console -allowdebug -hijack +map $file

This command launches Steam, then Source SDK Base 2006 (AppID: 215) with these command line applied, then load the compiled map. Replace the AppID if you have another game.

Note:By default, using "$game_exe" will cause the game would crashes at startup (because it was launched without Steam even with -steam, preventing the game from mounting depot VPK files). A workaround is to run the Steam executable. This might not be the issue if the depot VPK files are already extracted.

Important:If your Source 2006 game does not require Steam to run, and does not use depot VPK, or if you chose to not run the game after compiling map, you can skip this step.

8. Click "Close" on the Run Map window (this would save the compiler's parameters).

9. (Optional, but recommended) Add detail props and RAD file

Copy the detail.vbsp and lights.rad file from Half-Life 2 (latest version) or one from and paste it to the sourcetest folder. You can also go to

...\common\SourceSDK\vpks\depot_211_dir.vpk\game_content\<game-name>\<gamedir> and extract both files to sourcetest folder.

10. Done.

Important:Games that run on Source 2007 - Source 2013, included textures (such as 2D Skybox tool texture) that might not be available on previous version of Source (Source 2006). So it's recommended to run both Source 2006's Hammer and Hammer++, and check see if the same texture does exist in previous Source using Texture Browser on Source 2006's Hammer.

Note:Lighting in Source 2006 might be brighter compared to Hammer++ lighting preview (or Source 2007 and later), due to differences in LDR and HDR lighting.
