I hate love this name. A standalone C++ QT editor for Forza vinyl groups and liveries. Does not modify the game memory in runtime. We are not responsible for any damage done to your groups/liveries, use at your own discretion. Preferred communication is via Discord Channel, but you can leave the issue here as well.
Design vinyl groups in 2D, then inspect the finished livery on the car in a live 3D preview.
- Import/export to Forza proprietary binary format.
- Save/load project to json files.
- Full transformations for shapes and groups.
- Custom groups, reusable in multiple projects.
- Add raster or SVG image overlays as guide layers.
- Direct shape parity with the game engine.
- 3D car preview with live livery projection; auto-loads the matching car model.
- Blazingly fast perfomance thanks to C++.
Download the latest release, launch ForzaLiveryStudio.exe. Read manual for keyboard shortcuts and tools guide.
Configure all the windows as you need them and press Window -> Save Layout. If you want to rename the default shapes, go to assets/vector/shape_names.json.
All settings as well as custom groups are stored in your QSettings, in the registry HKEY_CURRENT_USER\Software\ForzaTools\ForzaLiveryStudio.

The import/export for groups is fully supported, core functionality in place. Source-backed liveries can be imported, previewed in 3D on a car model. The icons are handmade, we need a proper designer, I know they are ugly but at least we wont get sued. Livery import/export may have some shape transform mutations due to alingment issues, create an issue and attach a livery if that happens, we will investigate.
