Missing faces when upgrading Blender

Questions & Answers
1

Hello people,

I was originally using blender 2.62 in Unity 4.0.1f2, but updated Blender to 2.66 because it can use N-gons. However, when I imported the model, it was missing two faces. There is no problems with normals.

By accident, I opened the model from Unity and found that Unity still was using the blender 2.62 (2.62 cannot see the two faces because the faces had more than 4 edges).

I was wondering if there is a way to tell Unity which version of Blender to use?

Thanks

Re import your new updated model into unity.

Found the answer using mixed ideas from others:

  1. Go to the Assets folder
  2. Right mouse click Blender models
  3. Click on “Open with…”
  4. Click on “Choose Default Program…”
  5. Choose the Blender 2.66 (It will not work if the program are of the same name; change the newer to Blender266.exe)
  6. Now Unity3d would be “forced?” by Windows to use Blender 2.66
  7. Save As the model in Blender 2.66
  8. The model will now be updated

Thanks for the ideas Hyperion and angrycarrots.
