So far, I've had little success in getting a worthwhile iOS build from Unity 5 beta 9. 1) Any build I have tried with a Canvas simply hasn't worked. Got to the loading screen, then it freezes (and even freezes XCode that's attached and debugging it, bizarrely enough). Deleting the Canvas allows the build to work, but of course we are then lacking in GUI.... has anyone had success getting the UI to build in 5.0b9? 2) Any object in the scene whose appearance depends on reflection probes just looks black with a few highlights, as if the RP's are just showing all black. Reflection probes are expected to work on iOS, aren't they? 3) Performance on even an extremely simple scene is abysmal. With almost no script, and only 5 objects in the scene, the game runs at less than 20 fps. This is on an iPad 4, which would run a much more complicated scene without PBS at 60fps without breaking a sweat. Is this extreme drop in performance the expected tradeoff for using PBS? It seems.... a little much. (The scene does also have realtime soft shadows, but I've done the same on, again, much more complicated scenes at much higher framerates.) I've considered the possibility that the reason for 2 & 3 is that it's background rendering the reflection map for the probe, but the issues persist no matter how long I leave it running.
