unity3d GUITexture does not display the problem

1. The coordinates of the default position are relatively large and adjusted to X: 0.5 Y: 0.5 is the center of the screen.

2. There is no GUILayer component in the default first-person controller, and GUITexture will not be displayed without it. That is, add a component GUILayer to the camera Main Camera, location component->rendering->GUI Layer.

3. It is a scale problem, the default is 1.1.1
