bspguy

A tool for editing GoldSrc maps without decompiling.

Usage

To launch the 3D editor, drag and drop a .bsp file onto the executable, or "Open with" bspguy, or run bspguy <mapname>

See the wiki for tutorials.

Editor Features

• Keyvalue editor with FGD support
• Entity + BSP model creation and duplication
• Easy object movement and scaling
• Vertex manipulation + face splitting
  • Used to make perfectly shaped triggers. A box is often good enough, though.
• BSP model origin movement/alignment
• Optimize + clean commands to prevent overflows
• Hull deletion + redirection + creation
  • clipnode generation is similar to -cliptype legacy in the CSG compiler (the worst method)
• Basic face editing

The editor is full of bugs, unstable, and not all actions can be undone. Save early and often! Make backups before experimenting with anything.

Requires OpenGL 3.0 or later.

First-time Setup

1. Click File -> Settings -> General
2. Set the Game Directory to your game folder path (e.g. D:/Steam/steamapps/common/Half-Life/), then click Apply Changes.
   • This will fix the missing textures.
3. Click the FGDs tab and add the full path to your game's fgd file(s) (e.g. D:/Steam/steamapps/Sven Co-op/svencoop/sven-coop.fgd). Click Apply Changes.
   • This will give point entities more colorful cubes, and enable the Attributes tab in the Keyvalue editor.

bspguy saves configuration files to %APPDATA%/bspguy on Windows.

Command Line

Some functions are only available via the CLI.

Usage: bspguy <command> <mapname> [options]

  info      : Show BSP data summary
  merge     : Merges two or more maps together
  noclip    : Delete some clipnodes/nodes from the BSP
  delete    : Delete BSP models
  simplify  : Simplify BSP models
  transform : Apply 3D transformations to the BSP

Run 'bspguy <command> help' to read about a specific command.

Building the source

Windows users:

1. Install CMake, Visual Studio Community, and Git.
   • Visual Studio: Make sure to checkmark "Desktop development with C++" if you're installing for the first time.
2. Open a command prompt somewhere and run this command to download the source code (don't click the download zip button!):

    git clone --recurse-submodules --shallow-submodules https://github.com/wootguy/bspguy
   

3. Download GLEW (choose the Binaries Windows 32-bit and 64-bit link) and extract the glew-x.y.z folder into the bspguy folder that was created in the previous step. Rename the glew-x.y.z folder to glew.
4. Open a command prompt in the bspguy folder and run these commands:

   mkdir build && cd build
   cmake ..
   cmake --build . --config Release
   

   (you can open a command-prompt in the current folder by typing cmd into the address bar of the explorer window)

Linux users:

1. Install Git, CMake, X11, GLFW, GLEW, and a compiler.
   • Debian: sudo apt install build-essential git cmake libx11-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev libgl1-mesa-dev xorg-dev libglfw3-dev libglew-dev libxxf86vm-dev
2. Open a terminal somewhere and run these commands:

   git clone --recurse-submodules --shallow-submodules https://github.com/wootguy/bspguy
   cd bspguy
   mkdir build; cd build
   cmake .. -DCMAKE_BUILD_TYPE=RELEASE
   make
   

   (a terminal can usually be opened by pressing F4 with the file manager window in focus)
