Here are some tips to address common questions seen by people first learning to use the Unity engine. If you're reading this page, that's weird, as I would've probably linked you directly to the relevant page.
While cruising the Unity forums offering help to newbies, I frequently come across the same rookie mistakes and newbie questions. Some of the answers to these questions involve longer writeups than I'm willing to do repeatedly every time the question comes up, so it only made sense to throw the answers to the most common issues on a common easily-linkable page.
My name is Ray Nothnagel, though you may know me as StarManta from the forums or around the internet. I've been developing with Unity since version 1.5.1, back in fall of 2006. An independent contractor for most of that time, I now work fulltime for Nick Games.
