I created simple object with some vertex groups and shape keys and added keyframes based on the shape keys. I have problem with exporting this animation to unity. It just shows that there is only one frame in the animations section of this prefab. Do you have any idea what may be source of this problem. I'm new to blender and unity so I might have done some stupid mistakes. I watched many tutorials about exporting, but all of them were about exporting animation with bones.
