Importing assets

1. Export your model for Unity
2. Remove the .json file ending of all your created json files, otherwise Unreal Engine will get confused
3. Drag and drop the .model3 file into your content browser, and the system will generate all the assets needed

Using the model with UMG Images

1. Have your model imported
2. In the Graph of the UMG Widget call the function SetBrushFromLive2DModelMotion with the UMG Image and the Motion that should be displayed.
   • It is best to save the model motion into a variable, especially for the follow up steps
3. In Construct don't forget to call StartMotion on your Model Motion.
4. In Destrcut don't forget to call StopMotion on your Model Motion.
