BSPSource
BSPSource is a VMEX-based map decompiler for Source games. It converts BSP files back into VMF ones that can be loaded in Hammer. It also includes numerous bug fixes over VMEX and new features for doing the conversion, such as extracting embedded assets, processing multiple BSPs at once, and more.
Note:Decompiled maps aren't identical to the original VMF files that were used to compile them, and often present issues such as invalid geometry solids or misplaced areaportal brushes.Note:Some maps protected from decompilation prevent the conversion. However, VMEX "Protection methods" like using No_decomp 1, tools/locked and the obfuscation shape will be ignored. A warning will pop up, but it will decompile anyways.Console Commands
usage: bspsrc [options] <path> [path...]
Note: BSPSource must be ran with java console via like java -jar <jarfile> args1 args2 etc. Note: Options must come first, example: java -jar "bspsrc.jar" -o "D:\programs x86\vmfs" "D:\bsps\arena_badlands.bsp"
Which will decompile arena_badlands.bsp and put the vmf into the path given. | Cmd? | Description |
|---|---|
| -d | Enable debug mode. Increases verbosity and adds additional |
| -h,--help | Prints the commands |
| -l <file> | Use a text files with paths as input BSP file list. |
| -o <file> | Override output path for VMF file(s). Treated as directory if multiple BSP files are provided.
default: <mappath>/<mapname>_d.vmf |
| -r | Decompile all files found in the given directory. |
| -v | Print version info. |
| -no_areaportals | Don't write func_areaportal(_window) entities. |
| -no_brush_ents | Don't write any brush entities. |
| -no_cubemaps | Don't write env_cubemap entities. |
| -no_details | Don't write func_detail entities. |
| -no_ladders | Don't write func_ladder entities. |
| -no_occluders | Don't write func_occluder entities. |
| -no_overlays | Don't write info_overlay entities. |
| -no_point_ents | Don't write any point entities. |
| -no_rotfix | Don't fix instance entity brush rotations for Hammer. |
| -no_sprp | Don't write prop_static entities. |
| -force_manual_areaportal | Force manual entity mapping for areaportal entities |
| -force_manual_occluder | Force manual entitiy mapping for occluder entities |
| -brushmode <enum> | Brush decompiling mode:
BRUSHPLANES - brushes and planes ORIGFACE - original faces only ORIGFACE_PLUS - original + split faces SPLITFACE - split faces only default: BRUSHPLANES |
| -no_brushes | Don't write any world brushes. |
| -no_disps | Don't write displacement surfaces. |
| -thickness <float> | Thickness of brushes created from flat faces in
units. default: 1.0 |
| -bfacetex <string> | Replace all back-face textures with this one.
Used in face-based decompiling modes only. |
| -facetex <string> | Replace all face textures with this one. |
| -no_texfix | Don't fix texture names. |
| -no_tooltexfix | Don't fix tool textures. |
| -appid <string/int> | Overrides game detection by using this Steam Application ID instead.
Use -appids to list all known app-IDs. |
| -appids | List all available application IDs |
| -format <enum> |
Sets the VMF format used for the decompiled maps: AUTO - Automatic OLD - Source 2004 to 2009 NEW - Source 2010 and later default: AUTO |
| -no_cams | Don't create Hammer cameras above each player spawm. |
| -no_lumpfiles | Don't load lump files (.lmp) associated with the BSP file. |
| -no_prot |
Skip decompiling protection checking. Can increase speed when mass-decompiling unprotected maps. |
| -no_smart_unpack |
Disable 'smart' extracting of embedded files. Smart extracting automatically skips all files generated by vbsp, that are only relevant to running the map in the engine. |
| -no_visgroups | Don't group entities from instances into visgroups. |
| -no_vmf | Don't write any VMF files, read BSP only. |
| -unpack_embedded | Unpack embedded files in the bsp. |
