Cardboard Build failed

Greetings,

I tried to build the cardboard-unity-demo that comes with the unity-SDK but encounter some problems.
I also tried my own scenes but had the same issues (see pic.).

I´d appreciate any help - unfortunately I´m 3D-designer and no coder, so that you have to be very patient with me. :slight_smile:

I already did a google and forum search on this without success.

Thank you very much!

Chris
