Can't import a simple Blend mesh

Hello, I’ve made a [60546-car-hatch-blend.zip|60546] in Blend and I can’t import it to Unity.

When I click the mesh file in the project menu and open the inspector, I see this:

If drag the mesh file to the scene panel, I get the “operation not allowed” cursor.

Any suggestions? Thanks!

Actually, Unity is perfectly fine with using .blend files. They are also the only format I use, since I don’t want to go through the trouble of converting the files every time I make a change.

Maybe try enabling Read/Write enabled and Import Blendshapes, since that’s what I have.
I wrote this answer because I do not want to have to have you go through exporting the file every time you adjusted a normal or something. It would be awesome if you commented on this to tell me if it helped.
