Background #

Momentum Mod ships with a customized build of Hammer (named “Strata Hammer”) which includes some, but not all of Hammer++’s features. Our development has been geared more towards stability than new features, with a focus on porting to Qt for cross platform UI and bug fixing. While Strata Hammer should be perfectly usable (and we appreciate testers), it will be a while until Hammer++ features like accurate lighting preview are fully implemented. If you prefer using Hammer++, that is completely reasonable and this guide should get you set up.

The Garry’s Mod build of Hammer++ is recommended due to it being much easier to set up. The CS:GO build will require more tools and disk space to set up, but is required for some shaders such as 4WayBlend.

Hammer++ for Counter-Strike: Global Offensive #

Prerequisites:

• GCFScape
• Hammer++ CS:GO Build
• About 32 GB of disk space (depending on how many games are mounted)

Hammer++ Configuration #

1. Opt into the CS:GO legacy branch in Steam by right clicking Counter-Strike 2 -> Properties -> Betas -> Select csgo_legacy - Legacy Version of CS:GO
2. Install GCFScape and extract the Hammer++ .zip file into your Counter-Strike Global Offensive\bin folder.
3. Run hammerplusplus.exe
4. Copy the following configuration:

Mounting Games #

In order for Hammer++ to load content from the various games that Momentum Mod mounts, follow these steps:

1. Extract materials, models, and sounds from .vpk files:
   • Extract Counter-Strike Source\cstrike\cstrike_pak_dir.vpk into Counter-Strike Global Offensive\csgo\mounted_content\cstrike_content
   • Extract Portal 2\portal2\pak01_dir.vpk into Counter-Strike Global Offensive\csgo\mounted_content\portal2_content
   • Extract Team Fortress 2\tf\tf2_misc_dir.vpk and Team Fortress 2\tf\tf2_textures_dir.vpk into Counter-Strike Global Offensive\csgo\mounted_content\tf2_content
2. Mount Momentum Mod content by running this command in a command prompt: mklink /D "<path to steam games>\Counter-Strike Global Offensive\csgo\mounted_content\momentum_content" "<path to steam games>\Momentum Mod Playtest\momentum"
3. Open Momentum Mod Playtest\momentum\gameinfo.txt and copy the following contents into the SearchPaths section:

game        "csgo/pak01_dir.vpk"
game        "csgo/mounted_content/cstrike_content"
game        "csgo/mounted_content/portal2_content"
game        "csgo/mounted_content/tf2_content"
game        "csgo/mounted_content/momentum_content"

4. Open Hammer++ and the content from these games should load now.

Warning: If Hammer++ crashes on startup, you may have to delete the particles folders that were extracted from the .vpk files.

Lights.rad Setup #

In order to support light emitting textures from Portal 2, copy the contents from Portal 2\portal2\lights.rad and paste them into Counter-Strike Global Offensive\csgo\lights.rad
