Creating an Ase2 Source asset
The Ase2 source asset is the single point of truth that links your .aseprite file to Unreal.
What is a source asset
An Ase2 source asset wraps a single .aseprite file. All sprites, spritesheets, flipbooks, and slices are generated from it, and reimporting the source asset updates everything downstream.
Create one
- Right click in the Content Browser
- Choose Miscellaneous then Ase2 Source Asset
- Select your .aseprite file when prompted
- Name the asset and confirm
Key properties
- Source file: the tracked .aseprite path
- Import settings: which asset types to generate
- Output folder: where derived assets are placed
Keep the source asset alongside its derived assets so reimport stays predictable.
