We are developing our project using Unity. We pre-ordered Unity 5, so few days ago we got an invintation for Unity 5 beta testing. After that I upgraded my Unity version (removed old, install new one) to 5. Everything went fine, since I created new scene. Just added Terrain to MainCamera and Directional Light (added to scene by default) and thats all. I saved scene, click File->Build Settings, added current scene to build list and click “Build”. And process stuck on my new scene with : “Building level 7 : TestScene2 (Enlighten - Clustering)”. It is first time then I am trying to add scene after updating to version 5. Building for PC,MAC and Linux Standalone.
Encountered the same problem, I think you need to you need to wait for Unity to compile Enlighten- Clustering before you build the scene. You can see a blue progress bar in the bottom right of the screen. I believe this function has to do with Occlusion Culling. My project just finished loading Enlighten-Clustering, and now it is doing the same thing with Enlighten- Visibility. I’m building this on a very slow computer- this process has taken almost an hour. Will report back when I finally get around to building my scene.
The answer: In the Lightmapping panel, turn off GI workflow > Iterative, and Turn on GI workflow > On Demand. This will allow Unity to compile the Oculus Rift Player.
