EDITOR PLUGIN
Ase2UE
Import Aseprite art directly into Unreal Engine Paper2D — spritesheets, flipbooks, slices, and source data in one repeatable workflow.
WHAT IT DOES
One source asset. Native Unreal output.
Ase2UE connects your .aseprite file to Unreal through a single Ase2 source asset. From it, the plugin generates Paper2D sprites, spritesheet textures, and flipbooks that behave like any other native asset.
When your art changes, you re-import the source asset and every derived sprite, flipbook, and slice updates with it. No manual re-slicing, no broken references.
Who it's for
Built for teams and solo devs living in the gap between Aseprite and Unreal.
Aseprite users
If your art lives in Aseprite, your spritesheets, tags, and slices come across exactly as authored.
Paper2D developers
Sprites and flipbooks land as native Paper2D assets, ready to drop into your scenes and Blueprints.
2D game teams
A repeatable import pipeline means artists and engineers stop fighting over manual asset wiring.
Key features
Everything you need to move 2D art into Unreal without the manual steps.
Sprite & spritesheet import
Frames are sliced automatically with pixel-perfect UVs from grid or packed sheets.
Flipbook import
Aseprite animation tags become Paper2D flipbooks with per-tag frame rates.
Slice import
Named Aseprite slices import as assets, including 9-slice configurations.
Hitboxes & sockets
Slices named by convention become hitboxes, hurtboxes, and sockets in Unreal.
Source asset data
A single Ase2 source asset tracks your .aseprite file and all derived assets.
Repeatable reimport
Change the art, click reimport, and the whole asset tree updates in place.
Workflow overview
From a fresh install to live assets in four steps.
Install the plugin
Add Ase2UE from Fab to your project and enable it in the Plugins window.
Set the Aseprite path
Point the plugin at your Aseprite executable so it can read source files.
Create a source asset
Create an Ase2 source asset from your .aseprite file in the content browser.
Import & iterate
Generate sprites, flipbooks, and slices — then reimport whenever art changes.
