Blender to Unity basic knowledge and tutorial suggestions.

Iv finally got some models and stuff i want to send over to Unity to create a game. (Im very new to Unity and want to make a some test build stuff before i actually start on the actual project)

But before i go making a mess several things suddenly got me concerned when reading on how to make a first person game and that was the mention of constraints. I have searched for theanswer to my question about Blender models needing the constraint modifiers or any others “attached” to them before importing into Unity and causing me trouble and frustration.

I know its silly to be asking this sort of question but i really can’t find the answer to it.
Also, would anyone know of some good Unity game development tutorials that i could use to help me in case of future problems.

-Thanks!
