I’m fairly new to Unity and 3D game programming in general, so maybe there’s an obvious fix here, but I can’t find it. After downloading Blender, I made a model to use as a character. The character’s body is made up of fifteen pyramid shapes (hey, it’s my first try!), and two of them are having a strange issue. I’ve rigged the character and everything, but before adding animations of any kind, after just dragging the model into the scene and looking at it from different angles with the 1st Person Character Controller, the upper right arm polygon and the right hand will always turn based on the camera’s position. Everything else is standing still, like it should, but these two parts always face towards you. I’ve tried saving the model as a .blend and as a .fbx, but both yield the same results. A little bit stuck at this point, anyways. Thanks in advance for your time!
I guess pictures would be helpful to sort of show the problem I’m having. Here’s the model from different angles in Unity. This didn’t show up at all in Blender. Look at the upper right arm, the one on the left side of the image. Depending where it’s viewed from, it changes it’s angle. Any ideas why???
It seems I can’t upload fbx files here, but if anyone thinks they could take a look at it to help me I’ll be glad to provide a download.
Got some help in IRC, this is fixed now.
What was causing the problem?
Turns out it wasn’t actually pieces rotating, but an issue with the normals. I had the ones for that segment pointing inwards instead of outwards (newbie mistake,I know). That caused them to only show up from the wrong side, which looks a little like rotating.
Oh yeah, that will do it. Glad you got it figured out. 
Thanks!
