Create stereoscopic view

Hi everyone!

I found this tutorial link text and I'm trying to do the various steps and the stereoscopic view, but I have some problems!

1. Into the first picture there are two Texture in the project: Texture - Left eye and Texture - right eye..How can I create these?

2. In the second part of tutorial, He created a new camera, but it isn't' in conflict with the first person camera? How can I apply the two panel to the First person camera? I created the two panel without texture and the stereo camera but when I cliked play in "Island Demo" the main camera is "First person controller prefab".

Thank's a lot and sorry for any mistakes of calligraphy!
