Aventurine: League Tools

Aventurine is a Blender addon by Bud and Frog (Divine team) that adds native support for League's file formats. It's the reason Blender is now a real option for League modding instead of a workaround.

How to find it inside Blender

2. Press N to open the side panel.
3. Click the Aventurine LoL tab.

All import / export buttons live in this panel.

Import and export

• Use the buttons in the Aventurine LoL panel to import .skn, .skl, and .anm files.
• Before exporting, double-check that the right armature or mesh is selected.

Physics simulation

The physics tools are off by default to keep the panel clean.

1. Go to Edit → Preferences → Add-ons → Aventurine.
2. Tick Animation Tools.
3. A new Animation Tools tab appears in the side panel.

Use it to add secondary motion to hair, cloth, and accessories without hand-keyframing. You can also select all bones at once for physics collision setup.

The addon includes a built-in motion guide for hair physics. Open the Animation Tools tab to follow it.

Animation retargeting

The LoL Retarget option lets you move an animation from one rig to another. Useful for:

• Adapting an animation to a custom rig.
• Sharing animations across champions.
• Testing animations on different character models.

Enable it in the addon preferences first.

When to use Aventurine vs Maya

• Use Aventurine + Blender if you don't want to pay for Maya, or you already know Blender.
• Use Maya + lol_maya if you want the most established workflow, the largest tutorial library, and a polished rigging pipeline.

Both work. Pick what you'll actually use.
