TrenchBroom vs WolvenKit

TrenchBroom is a free level editor for brush-based engines such as Quake, Quake 2, and Hexen 2. It provides a 3D workspace alongside up to three 2D views. Brush editing includes vertex changes, clipping, scaling, shearing, and constructive solid geometry operations for merging, subtracting, or hollowing shapes. A UV view handles textures and supports multiple material collections. The entity browser accepts drag-and-drop placement and definitions from FGD, ENT, and DEF files, while model display includes mdl, md2, md3, bsp, and dkm formats. An issue browser filters map problems, helps resolve them, and offers automatic quick fixes. TrenchBroom can call external compilers and launch game engines, but those compilation tools are separate. It supports several Quake, Valve, Hexen 2, and package formats. The 2026.2 requirements list Windows 10 1903+, Linux with glibc 2.33+, or macOS 13+, with OpenGL 2.1 and GLSL 1.2 hardware.

WolvenKit is a free, open-source modding tool focused on Cyberpunk 2077 and REDengine 4. It can browse, extract, modify and repack game files into archives for use in the game. The Asset Browser previews meshes and textures from base-game or user-generated archives. Its RTTI-based File Editor reads and saves REDengine files, handles in-place buffer data, and converts game files to human-readable JSON and back. Project Explorer organizes files and opens source assets such as blend, PSD and XCF files. Asset conversion tools cover listed texture and model formats, with Blender one-click imports for shaded Cyberpunk meshes. Stable and nightly builds come through GitHub releases. Windows 10/11 64-bit and Linux are supported, although Linux compatibility is described as unstable and not guaranteed. The latest .NET 10.0 runtime and x64 architecture are required.
