Hi, this is my first post, I think this is a basic doubt, I create my terrain, but when I play my terrain I can't see in window game and I can't navigate in my application, I see a Small picture and I can't navigate for she.
If you are only seeing a bluish screen when you play, you might have to move your camera (or terrain) using the x, y and z axes to make your terrain appear.
Yeah, just drag a first person controller prefab into your scene view and then when you play your game, use the arrow keys or a-d-s-w keys to move around and mouse to look.
