grzyClothTool is a GTA V modding tool suite consisting of two main applications: CodeWalker (a WinForms-based game file viewer/editor with DirectX 11 rendering) and grzyClothTool (a WPF-based clothing addon manager using MVVM pattern). The tool enables users to import, preview, organize, optimize, and build GTA V clothing assets for FiveM/singleplayer/AltV platforms. Key features include 3D asset preview via CodeWalker integration, duplicate detection, texture optimization, auto-save functionality, and project management. The architecture separates concerns with shared libraries (CodeWalker.Core), plugin support via MEF, and navigation systems for view switching. Data flows involve scanning game files, importing assets (.ydd/.ytd), organizing via tags/groups, resolving conflicts, optimizing resources, and building final addon packages.
