Hi everyone!

A few days ago I released **Quick AO Lightmapper** for Babylon.js Sandbox. After seeing the interest and potential, I decided to bring it to the Three.js ecosystem as well.

The Chrome Extension is now available for **Three.js Editor** and works directly inside:

[https://threejs.org/editor/](https://threejs.org/editor/)

No exports. No external software. No complicated workflows.

Simply load your model, bake Ambient Occlusion, and see the results applied instantly in the viewport.

@Immugio Thank you! I really appreciate the support.

I’m happy to hear it’s working well for your models so far. I’m actively developing it and releasing updates quite frequently.

The latest version also includes a new Unity Extension (available on [Itch.io](http://Itch.io)) that connects Unity directly with AO Lightmapper for automatic AO generation and asset optimization workflows.

Feel free to share any feedback or suggestions as you continue testing it. User feedback has been incredibly valuable in improving the tool.

Thanks again! 🙂
