How to spin Imported FBX model 360* in unity3d

Question

I have been trying to spin my imported wheel from blender 360* but when I do it, it doesn't rotate on the center (on one spot). I'm using C#.

I have tried this:

transform.Rotate(Vector3.forward, 5f - 90);

But this doesn't spin on one spot.

Answer 1

That is probably because your model's origin isn't in its center. You need to either

1. position your model in Blender so that its center is in the global origin

or

2. change the call to RotateAround which you can then for an example pass in collider.bounds.center to rotate around your collider's center position.
