Why are these mesh white and does not appear in rendering? I'm trying to edit this intro https://www.youtube.com/watch?v=fya4qXcCzeU, but the mesh contained in the intro does not appear in rendering, the mesh appears all white in preview.

In the video contains the link with the file blender.

Thanks to all who tried to help me

Cheers!
While you are in Object Mode press W and then Clear All Restrict Render. Hope it helped
