Full walkthrough

This guide takes you from your first tool install to a finished, published skin. Follow the parts in order.

How the pipeline works

Modern skin making follows one path. Flint covers most of it in one window.

1. Extract the skin's files from the game.
2. Preview the model, textures, and VFX.
3. Edit what you want to change: model, textures, particles, or sound.
4. Validate the mod and fix common bugs with Hematite.
5. Pack the mod into a .fantome or .modpkg file. These are the mod package formats a skin manager installs.
6. Install it with a skin manager to test in-game.

Each part below maps onto one of these steps.

Getting started

Tools you need

Start with these three. They cover most of the work:

• Flint: extract, preview, edit, validate, and pack. The all-in-one app.
• Jade: a focused BIN editor for when you want one.
• Quartz: VFX recoloring, porting, and light audio work.

You will also want:

• The Tools overview for everything else.
• LtMAO is optional. It is an older toolpack, kept as a fallback for batch jobs and full soundbank work.

Step-by-Step Walkthrough

Part 1: Flint

Explore League's game files with Flint. Learn the modding basics and set up your project folders.

Includes:

• File exploration
• Modding fundamentals
• Project setup

Part 2: Hacksaw

Recolor existing visual effects using a visual palette system. No coding required.

Part 3: Replacing a Model (Maya or Blender)

Replace a champion model with Autodesk Maya and the LoL Maya Plugin. For Blender, see the Blender model swap guide.

Important Notes

• Install LoL Maya first
• Do not delete faces, vertices, or edges after binding the mesh
• On first import of .skn / .skl files, use Import, not drag-and-drop
• Ensure separated materials and meshes are enabled

See the Maya Error List.

Part 4: Maya Materials, Submeshes, and Bin

Understand how materials work in Maya and how to reference them inside .bin files using MaterialOverride.

Part 5: Matrix and Idle Particles

Scale, rotate, and move visual effects using transformation matrices. Add idle auras or passive visual effects.

Includes:

• How to place a VFX system (important)
• Code used in this tutorial

Part 6: Particle Systems and Triggered VFX

Trigger visual effects using:

• Animation events
• Game logic (PersistentEffectConditions)

Part 7: Voiceover and Sound Effects

Replace voiceovers and sound effects, such as spell sounds or taunts.

Part 8: Retargeting Animations

Transfer animations from other games or champions (for example, Fortnite) to League rigs.

Tool

Part 9: League Materials (Glow and Toon Shader)

Apply League-style materials such as Glow and Toon Shader to your custom skins.

Part 10: Repathing and Publishing

Repath your mod so it lines up with the current game files, then publish it.

Pack and export. In Flint, export your mod as a .fantome or .modpkg file.

Repath options. If a path is wrong, or a patch broke the mod, repath it with League Mod Repather or Quartz's Bumpath page.

Install and test. Load the mod in a skin manager like LTK Manager or Celestial, then test it in a custom game.

Extras

Adding Bones and Physics (Hair, Tails, Capes)

Add bones and physics-based motion to your skin.
