I have the basic things I need for the terrain, and I also already have added my First Person Controller Prefab. As I've seen from some photos, other users used a capsule to model their characters. In my opinion, I also think that the capsule is the best way to represent a character, but the problem is that, how do I create a character from the said capsule? And by the way, I'm a beginner.

P.S I would like the answers to please be simple yet elaborate. Thanks! :)
