What it is

Crowbar is a free Windows tool for modding GoldSource and Source Engine games. It can decompile, compile, and view models, as well as unpack, inspect, and search Valve VPK, Garry's Mod GMA, Vampire: The Masquerade - Bloodlines VPK, Tactical Intervention FPX, and Fairy Tale Busters APK packages. It can also pack folders into Valve VPK and Garry's Mod GMA files. Decompilation can recreate QC, mesh, animation, and procedural-bone files, while batch workflows can process a selected folder and its subfolders. Crowbar supports downloading Workshop items and publishing them for several games. The maker says Windows XP or later and .NET Framework 4 are required. Compiling models needs the game's authoring tools or SDK and its studiomdl.exe; viewing models needs authoring tools or an SDK and hlmv.exe. The latest release shown is version 0.74, dated February 2023. Help materials include guides, tutorials, reference resources, Discord, and Steam discussions.
