GearVR - VERY long initial loading time. REALLY long.

How long are we talking here, 10 minutes? an hour? Can you send the full logcat from a run with the issue (run "adb logcat > log.txt" and attach it here)? Are you using compressed textures and GLES2? Does the issue occur if you use GLES3 and force ASTC compression?

Not 10mins, but over 3mins.

I just deleted all the audio and script related assets from the scene and tested and it loaded quickly - it's not textures at all, but something in the scripts I think... perhaps the audio as well.

This doesn't happen in the Unity 4 build, but we were having audio problems with the 4 build, so had to upgrade.

Thanks. Logcat from one of the slow runs would help us narrow down the issue.

Ok - seems I figured it out - will get back with info...

Here we go: https://dl.dropboxusercontent.com/u/26496233/log.txt

EDIT: Just retried the Unity 4 version - loads in seconds. This is something Unity 5 has introduced.

Hmm, so to sum up the issues...

Unity 4 has an audio latency bug. Builds for S6 will work first time after install, but then the audio goes 'crunchy' and to relaunch it again you have to REINSTALL it - and it works once more. Not ideal.

Unity 5.1.2f works, but introduces LONG load times, due in part to a bug in 'Resources.Load' which is fixed in 5.1.3

Unity 5.1.3 and 5.2 will NOT build to GearVR and crash out during build with the following errors:

The primary one not seen in the above is:

UnityException: Plugin Bundle ID conflict detected!
Package com.oculus.Integration has conflicts with other plugins. See the Console for details.
UnityEditor.Android.PostProcessAndroidPlayer.ShowErrDlgAndThrow (System.String title, System.String message, System.Exception ex)

UnityEditor.HostView:OnGUI()

So it seems I am currently stuck until GearVR will build on a newer version than 5.1.3

I'll keep looking at the log, but the first thing I notice is:

D/Unity   ( 6781): Fragment shader compilation failed.

D/Unity   ( 6781): ERROR: 0:26: ':' :  wrong operand types  no operation ':' exists that takes a left-hand operand of type '3-component vector of float' and a right operand of type 'const float' (or there is no acceptable conversion)

D/Unity   ( 6781): ERROR: 0:26: '=' :  cannot convert from 'const float' to '3-component vector of float'

D/Unity   ( 6781): ERROR: 2 compilation errors.  No code generated.

The full shader is also dumped in the log to help you narrow down the issue.

Are you using 4.6.8? There was a known bug like you described with Gear VR audio in older builds.

Are you sure this isn't actually the above shader compilation error? I've used Resources.Load with 5.1.2f1 and earlier without problems. If Unity actually fixed a bug here, this is the first time I've heard and it would be great to get more detail about it.

Try changing the case of the O in oculus in the bundle ID.

So the bundle ID was a weird thing - it shouldn't have reset to the default, but it did. I changed that and that error went away.

The only issue with 5 now appears to be V long load times still :)

In any case I MAY have gotten Unity 4 working with the latest build! :D Just testing thoroughly.

Yup! Appears to work well in 4, so I'll stick with that for now :)
