Game freeze when loading from customer splash screen scene.

Hi, first I'm not sure if this related to unity technical preview.

I currently have unity personal. I made a scene to have a splash screen while my app menu is loading. Simple script call SceneManagement.LoadLevelAsync(current scene +1) in the start fonction. In the same scene I also have simple 3d gameobject that rotate to show user the game is loading.

My problem is once in a will (still happening to often), my app will freeze on my custom splash screen (no crash to main screen). I can tell it has freeze because the object is no longer rotating and the next "menu" scene is never shown. This happens about once every five time I launch the app.

I also notice I have more chance to run into this issue if I start the daydream app from my phone app list. It looks like the fact that the daydream app start at same time to tell user to put the phone in the headset and re-center the view will cause this issue to happen more often.

But I also have this problem when loading the app from daydream home but less frenquently.

I tried to find some clues with profiler, but it stops receiving information from my device when the game freeze.

Again i only have 2 script in my custom spash screen scene. One to load next level async. The other to rotate gameobject. I only test my game on pixel. Works great almost always at 60fps with some drop when loading/opening new scene. I setup player settings like told in the above thread. My texture compression, if relevant is set to ASTC which is giving my much better result with lightning. Most of my light are baked.

Can someone point me in the right direction to troubleshoot this problem effectively?

Thank you.

 

I reproduce my bug and got the logcat. First time trying to find error in this, and i see few error but I'm not sure which one i should be looking at.

That came to my attention. Can it be the cause my game freeze on launch. It is about the same time i experience the freeze on screen.

I also notice this in the log

Case 884461

 

Thank you for taking a look into this.
In the step to reproduce the freeze I forgot to mention something. After launching the app, daydream app will open to pair the controller. To save time I just press on recent app and go back on my app. The issue will also occur when pairing controller.

 

Yes I have upgrade gvr sdk to 1.2, it didnt fix the issue. I will try this tonight and let you know.
Thanks

 

I did comment out
audioSource.outputAudioMixerGroup = mixer.FindMatchingGroups("Master")[0];
in gvraudiosource. Still freezing 25% off the time while loading from splash screen scene.

 

No changes. I wasnt aware 5.6 beta include support for daydream, i will try it and let you know!

Not related to my problem:
I dont see any major issue with daydream support with 5.6 beta. Is there a reason i should keep using technical preview or should i just switch to the beta?

 

I just tried 5.6 beta and its kind of worst.

Still same issue, game is freezing while loading.

Btw I didn't mention camera is still able to follow head movement after the app freeze, only my next scene is never showing and my loading indicator (rotating 3d object) stop rotating.

My app crash to main screen 2 times while testing with beta. Maybe I was skipping the controller pairing too fast..

Also huge distortion in editor, but I also notice the temporary fix on the sdk page on GitHub.

 

I am still trying to debug this issue.
Using adb logcat -s Unity -s DEBUG when a freeze occur,
the last log is always ;
Unloading 4 unused serialized files (Serialized files now loaded: 0).

I dont have the same call when the game is loading fine, only when it freeze.

Could this be related to my issue?

The issue I have seems to be related to this. I tried setting up a empty scene at the beginning and from the empty scene I call SceneManager.LoadLevel() to start my splash screen scene. Then in my splash screen scene, I call my menu scene with loadlevelasync() because it needs to load a bunch of 3D model and UI while showing something moving (3d object) to let player know the gane is loading.

Adding the empty scene or calling system garbage collector before loading menu scene, didnt help. It seems to have reduce the occurance of the issue but it still happens.

 

Okay i did bug report with 5.6b10
Case 888160

 

Problem fixed, thank you for your assistance. I had an asset which include a few procedural texture that where build on level load which was slowing down loading and sometime crashing the game. I've built the textures instead of having them build on load and no more issue.
