Ocean created with Blender 2.64

I think you forget to pack the sunset texture into the blend file, my render result shows no red sky. Maybe the texture is not under a friendly license, but as the text does not say anything about this I assume you simply forget to pack it. This is the render result my machine produced: http://imageshack.us/f/24/33540658.jpg/
Oh, I am sorry... I do remember packing the sky though, that is weird....
I will look into it
