how do i import an animation from blender

i tried to import an animation from blender to unity and i just make like 500 copies in different angles so im wondering how i just import the animation

Are you importing the .blend file directly, or exporting it as an .obj and importing that? I got the many copies when I exported an animated model as .obj, but I was able to import the .blend file into Unity OK.

If you save the blender file in a folder under your Assets Folder the animations should automatically be attached to the object. They Will appear in the inspector view.
