Model not animate when changing timeline in Unity
I am working with Live2d 3.0 and successfully in import and make new model from Cubism editor to Unity. But when a prefab of model generated, I drop it in the scene and try to animated in Unity Animation Window, it didn't work. In detail, the model work perfectly when I hit button Play, but when I trying to adjust animation by timeline, it doesn't. Please check the screenshot.
Please point me out the mistaken or guide me to make it work, so I can add animation event easier and more exactly.
