OK, all working now.
With the visual studios update 2 and the new windows sdk everything seems to export perfectly now.
Managed to get my build working on my Xbox One today.
Wasn't running very well but I guess a big part will be down to the 500MB RAM limit we're restricted to at the moment.
Still amazing to have it running on console! Other than the slow down everything seemed to be intact. Controls were great and Web GL effects were all there.
All in all pretty awesome
