Import Normals Problem (Unity 3.1 to 3.2 update cause?)

Unity Engine
1

So I recently upgraded my unity version from 3.1.0 to the new 3.2. I have models that I am importing as assets into Unity (.obj files) and when drag them into the scene I am getting some funky discoloration with the imported normals. It looks something like this… (using an extremely simple model, only a few extrusions)

Notice the funky discoloration…
It should look like this…

Whats strange is that my design partner has the 3.1 version, and when he imports the exact same model with the exact same settings he is NOT getting the weird blotchiness…Was something changed with the way unity handles shading, lighting, or importing of normals between 3.1 and 3.2?

The only thing that fixes the problem is if i switch my normal settings from “import” to “calculate”… As i said before though, my friend with the 3.1 version does not have to switch to calculate for it to look correct.

Thanks for any help in advance :slight_smile:

Don’t know if this is your issue, but Autodesk FBX importer also plays a role in importing. I had weird stuff going on with some imports before, then when I upgraded my FBX importer it fixed the problem.

Hmm, i guess i could go ahead and try using an FBX, but a simple .obj should be plenty to preserve the correct normals… :confused:

.obj files go through the .fbx importer for some reason, and unfortunately the version used in 3.2 has some bugs that didn’t exist earlier.
