MBSPC

Modified BSP Converter ("MBSPC") which is a cmd map decompiler for Goldsource games, written in C++. It converts BSP files into sources AAS and .MAP ones that can be loaded in Hammer.

Features

• Works on 99% of the maps.
• Few bugs to fix in decompiled maps. (Invalid solid structure)
• Proper textures places
• Load huge BSPs
• Customizable decompile options

Drawbacks

• Complex shapes aren't decompiled perfectly, still need a lot of manual fixing, or redo from scratch.
• On windows 10 it works fine, on windows 7 some of you can get missing .dll errors, like "ucrtbased.dll".
• No GUI, command line only
• Only Tree-Based decompiles
• Does not automatically extract embedded textures
• Does not decompile overly complex maps (such as dust2_2020) or decompiles them with missing brushes.

Limitations

Important:Any commercial use of MBSPC without prior written consent by the original map author is prohibited.

bsp2aas <[pakfilter/]filter.bsp> = convert BSP to AAS
reach <filter.bsp> = compute reachability & clusters
cluster <filter.aas> = compute clusters
aasopt <filter.aas> = optimize aas file
aasinfo <filter.aas> = show aas file info
entlist <[pakfilter/]filter.bsp> = extract entity list
texinfo <[pakfilter/]filter.bsp> = extract texture list
output <output path> = set output path
threads <X> = set number of threads to X
cfg <filename> = use this cfg file
optimize = enable optimization
noverbose = disable verbose output
breadthfirst = breadth first bsp building
