A tool to generate normal maps for pixel art sprites and animations. Written in Rust, available as a CLI and a WebAssembly library. Normal maps let 2D sprites react to dynamic lighting. Ideal for 2.5D games. Features: Requires Rust 1.85 or newer. From this directory: The binary is available at target/release/spritefusion-sprite-normals. To install it locally: Without an output path, maps are saved beside their inputs as n.png. Run spritefusion-sprite-normals --help for every option. GIF and APNG inputs, and PNG sheets with --frame-size, produce three files: Frames are arranged in row-major order. delaysms contains [numerator, denominator] pairs in milliseconds. PNG sheets keep their layout and receive a default 100 ms frame delay. Source loop counts are not exported. Normal PNGs are data textures: disable sRGB sampling in your engine. Use artwork at its native pixel resolution. Generation estimates relief from color and shape; painted highlights can also become surface detail. Build…
