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.

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 Global Offensive\csgo\pak01_dir.vpk into Counter-Strike Global Offensive\csgo\mounted_content\csgo_content
   • 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/mounted_content/csgo_content"
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.
