unity-aseprite-importer
A Unity package written in C for importing Aseprite .ase and .aseprite files directly into Unity, built on Unity's experimental AssetImporter API. The importer fully reads the compressed binary Aseprite format in C and generates static sprite sheets, sprites, tilemaps, and animations. It creates non-dynamic animation files along with an animation controller. Editable metadata such as custom physics shapes can be refined using Unity's Sprite Editor. The tilemap generation uses extended padding to prevent line tearing between tiles, and new row-col tilemap naming rules are supported. Installable via OpenUPM using the package name io.tinu.asepriteimporter, through the OpenUPM CLI, or by adding the git repository URL through Unity's Package Manager. Ideal for Unity developers using Aseprite for 2D pixel art who want a streamlined workflow that avoids exporting spritesheets externally.
