Blender animations to Unity

I have a simple door open animation, but when I import the .fbx into unity and split the animation, there is no animation file. It’s a simple keyframe animation, no armature or anything.

Thanks,

And your question is?

I wouldn`t use an armature for a door. Animate the door in Unity.

I think, question is:
Why standard keyframe animation from blender isn’t imported to Unity…

Unfortunately this can be due to many reasons… and is a common question. Check this out, it may help: http://forum.unity3d.com/threads/40908-FAQ-Getting-skinned-animated-models-from-Blender-to-Unity3D

Unfortunatly I myself am getting used to the work-flow of importing models into Unity. The first reason may be because your door model is not parented to the armature. Second, I personally use vertex groups. So when you go to parent (CTRL+P) your model make sure you select “Automatically create vertex groups from envelops” or you can just manually create them via the vertex group option, just be sure the vertex group name and the bone names match. Finally I believe I read somewhere that ALL vertices’s must have a bone. So if you have a door frame and a door, you will need a door frame bone and a door bone (don’t quote me on this one unless you test it).
