Quick AO Lightmapper has officially been approved and is now available on the Chrome Web Store.

The extension integrates directly into Babylon.js Sandbox, adding a built-in Ambient Occlusion lightmap baker that works on top of your existing scene and allows you to preview results instantly inside the viewport.

Main Features

:white_check_mark: Import GLB and FBX (convert)

:white_check_mark: One-click AO lightmap baking

:white_check_mark: Direct integration with Babylon.js Sandbox

:white_check_mark: Automatic UV2 generation

:white_check_mark: Real-time viewport preview

:white_check_mark: Select specific meshes for baking

:white_check_mark: Denoising and seam-fix options

:white_check_mark: Download generated lightmaps instantly

The goal of the project is simple: make AO baking fast, accessible, and available directly inside the tools developers already use every day.

Free Tier Available

Quick AO Lightmapper includes a free tier that allows everyone to try the extension and use its core functionality.

For users who want to unlock the full experience, there is an optional support tier available through Buy Me a Coffee for just $4.

This contribution helps cover support, maintenance, bug fixes, and future development, while allowing me to continue building tools that benefit the Babylon.js community.

IMPORTANT - GPU PERFORMANCE

For the best baking performance, AO Lightmapper automatically detects and selects the most appropriate GPU available on your system whenever possible. No manual configuration is required for the desktop application.

For the Chrome Extension version (Quick AO Lightmapper), GPU selection is managed by the browser and operating system. To ensure optimal performance, it is recommended to configure your browser to use the system’s High Performance GPU.

Windows: Go to Settings → System → Display → Graphics, select your browser, and choose High Performance.

Linux: Launch the browser using the dedicated GPU (NVIDIA PRIME, Discrete Graphics, or your distribution’s equivalent option).

macOS: GPU selection is handled automatically by the system. For best performance, use the device connected to power and avoid power-saving modes.

The extension works on integrated GPUs, but a dedicated High Performance GPU can significantly reduce bake times and improve responsiveness.
