I made an ocean using this tutorial

https://vimeo.com/84903041 [vimeo.com]

Everything is fine on the first frame, but when it transitions into the second frame, the ocean becomes a light pink, the environment light goes away and the sky becomes dark. I get the unable to load texture on the ocean map and the environment map. I'd really like to know what causes this problem and solve it. I'd be very grateful for the solution.

Thanks in advance for your help.
