Cyber Engine Tweaks is a modding framework for Cyberpunk 2077 that injects a DLL into the game process to provide a Lua scripting environment, an ImGui-based overlay (console, TweakDB editor, settings, log viewer), and quality-of-life patches (disable vignette, disable boundary teleport, skip start menu). It hooks into D3D12 rendering and input systems, reverse-engineers the game's RTTI layer via RED4ext.SDK, and exposes game objects, functions, and the TweakDB to Lua scripts. Modders can place Lua scripts in a `mods` folder, which are executed in sandboxes with access to the full ImGui widget library (via sol_imgui) and SQLite databases (via lsqlite3). The architecture is monolithic—a single DLL orchestrates all subsystems (core initialization, hooking, scripting, overlay, reverse engineering, patching). External dependencies include LuaJIT, sol2, Dear ImGui, MinHook, spdlog, nlohmann/json, and TiltedPhoques library. The codebase is actively maintained but carries inherent drift risk due to hardcoded game offsets that must be updated per game patch.
