U5B9 is importing Blender objects wrong so I filed an official bug via the in-Unity bug reporter. I enclose the contents of that bug here to see if anyone else has insights into this or would perhaps like to discuss it. Thanks! Kurt Unity5 Beta bug: Blender import scale is incorrect. Description: Blender files imported to Unity 5.0 beta are imported at the incorrect scale. "Incorrect" in this context means "wrong from every previous version of Unity that I have used going back to Unity 3.5" Expected Results: Blender files imported in Unity5 are scaled the same as they are in Unity4 and earlier Actual Results: Blender files imported in Unity5 are too small by a factor of 100 times too small Steps to reproduce: 1. open Blender3D and save the default cube, which is 2x2x2 in Unity and Blender units 2. open Unity 4.5.4 and import the cube using default import settings. 3. Place cube next to a standard Unity3D cube primitive. 4. Notice it is the correct size. 5. Open Unity 5.0.0b9 Beta 6. Import the same original Blender3D cube using default import settings 7. Place cube next to a standard Unity3D cube primitive 8. Notice that the Blender3D cube is now extremely tiny, by a factor of 100x too small.
