## What it is
Laigter is an open-source desktop tool that automatically generates normal, specular, parallax, and occlusion maps from 2D textures, designed primarily for lighting effects on sprites in 2D games. It includes a live preview of how the generated maps will look in-game and is available on Windows, macOS, and Linux.

## Use cases
- generate normal maps for 2D game sprites
- create specular maps to add shine to sprites
- make parallax maps for 2D backgrounds with depth effects
- generate ambient occlusion maps for 2D textures
- preview dynamic lighting effects on sprites before exporting
- batch process 2D textures for use in 3D games

## When to avoid
- you need to generate maps for 3D meshes rather than 2D textures
- you need a fully automated pipeline or CLI integration rather than a GUI tool
- you require a maintained 2.0 rewrite with multithreaded performance, which is not yet available
