for a school project, I am trying to import a series of obj models scanned from a Kinnect and import them into blender as sequence of stills, and then after making changes, export them as an FBX to be used in Unity. I have tried using this stop motion addon to import the OBJs as a sequence, but when selecting .fbx when exporting, only a single frame (the first) is ever exported. Is there anything I am able to do to export as an animation?
If you can guarantee the same number of vertices will appear in the same order in each .obj file (such as a single character model exported to individual frames), you could accomplish this by interpreting the vertex movements mesh transformations on import. Otherwise, you're stuck with entirely separate objects on each frame.
I don't know of any off-the-shelf versions of this, though the stop-motion script you mention in your question could be modified to work this way (in particular, the bakeSequence() function which creates a separate mesh object per-frame).
