MSFS Livery Toolkit: create, paint, and compile MSFS liveries with no config files and no command line

Download the latest beta release View on GitHub

Key features

✓Automated livery setup: scans your installed aircraft, detects the profile, and builds a correct, sim-ready package structure for you.

✓One-click texture extraction: decodes compiled KTX2/DDS art back into editable PNGs, even specially compressed files other tools can't open.

✓Instant UV wireframes: generates a paint-alignment UV map straight from the aircraft's own 3D model.

✓Ready-made 2D paintkits: builds a layered Photoshop file from any aircraft's own textures and UV layout, even when no paintkit was ever published.

✓3D paintkits (experimental): exports the parts you are painting as a 3D model you can open in Blender or other 3D painting software, so you can see your artwork on the aircraft instead of working it out from a flat UV map.

✓Built-in 3D preview: see your paint on the aircraft as you work, without compiling or launching the sim, and see exactly which part of the airframe each texture covers before you start.

✓Rendered thumbnails (experimental): writes every thumbnail image MSFS expects, at the right size and with the right transparency, drawn from your own paint. No trip into Developer Mode and the Aircraft Capture Tool.

✓Seamless compile & package: builds a sim-ready package with the official MSFS SDK, no command line.

What it does

The toolkit takes you through the whole livery pipeline:

Create: pick an installed base aircraft, and the app detects its profile (2020 monolithic, 2024 monolithic, or 2024 modular) and builds out a correct, sim-ready livery package structure.
Work: choose which of the base’s textures to repaint, generate correctly-sized blank canvases or extract the base’s own compiled textures back to editable PNGs, and edit each texture’s compile flags. A built-in 3D preview shows your artwork on the aircraft as you paint, so you can catch a misplaced decal without compiling first. When the paint is done, the app renders your livery’s thumbnail images for you, so the sim’s own capture tool is one less thing to learn.
Compile: turn your PNG artwork into sim-ready DDS/KTX2 using the official MSFS SDK, build a full package ready to use in your community folder, then regenerate layout.json and launch the sim to test.

A project is a single deployable package that can hold one or many liveries sharing the same base aircraft.

Requirements

Windows 11 (64-bit)
Microsoft Flight Simulator 2020 and/or 2024
The matching MSFS SDK (installed through the sim’s Dev Mode)

(MSFSLayoutGenerator, which the app also needs, is now bundled - nothing to download.)

How it was built

Hobbyist Built: I am a livery painter, not a professional software developer. This toolkit was built to automate the tedious backend chores of package layout so we can all spend more time creating.
AI-Assisted Architecture: Because I lacked the coding experience to build a full Windows application from scratch, I used a personally funded Claude Pro subscription to bridge the gap.
Human-Driven Logic: This is not unthinking “AI slop.” Every workflow step, simulator profile rule, and configuration logic choice was explicitly designed by me based on real flight-sim SDK behavior and manually verified at every milestone. Countless man-hours have gone into this project, even with Claude writing the code.
Always Free: Leveraging these modern tools made it possible to build a polished desktop utility in my spare time and release it completely free to the flight simulation community. I will never monetize this app (besides entirely optional donations) or lock functionality behind a paid-for tier.

Support the project

I’ve funded this project out of my own pocket with a Claude Pro subscription. I will never monetize this application or offer a premium tier - I’m developing it as a perpetually free tool for the livery painting community. However, to keep enhancing and developing it, I would be grateful for any donations via my Buy Me a Coffee page.
