Update 4! V4 Better examples and Minor bug fix.
There are now 2 scenes. A 3d and 2d. I added a simple player movement script to get the camera to move around a bit, and added a simple rotation script to the camera in the 3d scene with 3d spheres. There was also a bug with the message box where the letters in the message box were not getting rotated properly on creation when the camera was in 3d mode. This is now fixed. I've also removed the automatic pixel perfect script that I had made from most objects and is off by default, as it was causing problems with movement. It should be fine to use on static objects, but moving things should not have it.
Removing the pixel perfect script from moving objects also made me decide that there's no reason to keep the old player camera prefab and just made 2 prefabs with the render texture. The overhead of a 64x64 pixel render texture is pretty low, so I don't see there being any problem unless the system you run the game on would have had problems running to begin with. The two camera prefabs are set up with orthographic and perspective as they should be. Just drag them into the scene.
I also made the folders a little easier to tell what's extra stuff that you can remove, and what's required for the camera system to work on it's own.
Anyway, that's this update! Probably the last, so... Enjoy!
