SpriteDicing

Keep only the unique textures subset in the final build. Ideal for VNs, where character sprites mostly differ in face expressions.

SpriteDicing is compiled into native library with C ABI making it embeddable to any game engine, framework or programming language.

Alternatively, standalone CLI tool is available for Windows, macOS and Linux; it'll produce atlases and JSON with the diced sprites specs.

SpriteDicing is authored in Rust programming language for best performance and reliability.

CLI tool supports input textures in multiple formats: PNG, WEBP, JPEG, BMP, TIFF, TGA and DDS.

Has plethora of options: atlas size limit, UV inset, padding, trimming, sprite pivot and more.

First-party plugin for Unity game engine with a dedicated editor UI; outputs native sprite assets.
