Resizing In Unity Does It Hurt?
I read that it is best to make sure the size of your objects are fairly exact in your modeling program before import into Unity. Does it really effect the engine if you resize objects in Unity?
Can you clarify when you're asking about? Import rescaling? Runtime?
Scaling an object can have an impact in several regards. Matthew Wegner, in one of the Unite presentations he's given (the video is on Unity's website), mentions that PhysX is less optimal when an object is scaled in engine (not with import settings), especially when instantiating an object.
Changing the import factor doesn't change the performance, but from my understanding scaling an object frequently by script will hurt your performance. See links below.

What about a one-time resizing when you bring the model into Unity? That's what I thought the OP was asking about.
It's my understanding that the biggest problem with scaling is recalculating the mesh, so doing that one time will not hurt as much, but physics are more expensive on an object that has been scaled in the editor or at runtime.
