Prefabs Breaking Between Levels and Builds

Hi, I posted this on the oculus forums, no reply as yet, so I imagine this might be more unity thing.

Here is what is happening.

I have a Unity FPS controller, arms with weapon parented to it, then a game object at the end of the weapon that spawns my projectiles. All of this is guided by head position etc.

This is a prefab dropped in multiple levels.

It works perfectly most of the time through all levels.

When I build a version of the game with multiple levels, say 4 or 5. It will only work correctly on 1 of the levels, and that is also random, it could be any level that it chooses.

When it breaks head movement no longer guides the direction of the projectile spawner so you effectively can't aim anymore.
Really giving me a lot of trouble at the moment, I wonder if anyone has any ideas?.

using latest runtime and unity 5.1 with VR mode enabled, standard assets not OVR or anything.

I can send along 2 example builds that show the issue if that helps. Thanks so much.

EDIT - Just to be sure I just got the latest unity patch 5.1.1p4 and upgraded everything. Same issue.
EDIT2 - This also happens when switching weapons, if weapon 1 is initially working and I switch to a new weapon, things break, switch back to first weapon, now broken also.

Here is a video of things working correctly, not that it helps, but you can see how it should behave. I'm using my eyeline / head movement to aim + jump etc. works well.

 

Hi, just updated to 5.1.2 to see if this fixed the issue and no luck still there.
Just submitted a bug report 713029.
Thank you

 

Since I have not heard anything on this, I wanted to add two things I have observed since.

1. Playing direct from the editor works every time correctly. It's when I build that things break with head tracking.
2. If I make a build with multiple levels and the first level does not contain my prefab, eg just a static camera without a controller, the level after that works correctly and then the rest break.

 

yeah, got fixed with new update

 

Thank you Ed, that sounds great I will try this out when the new patch is here and let you know either way. Thanks again for looking into this

 

I tried the new patch today, did not fix my issue unfortunately.
Since this problem has stopped me from progressing anywhere, I tried to track it down more and I think i have it.

I can repro this 100%, every time. It involves saving and opening levels. So since it's a long explanation I made a video of this. Hope it helps as it relates to VR and head position tracking. Seems that when I save and open levels things break and that would also explain why they don't work correctly when building multiple levels?.

Anyway here is what is happening.

 

Forgot to add that the temporary fix I found was to duplicate a broken game object, then everything is working, but If I close a level and re open it's all broken again. With 20 or so levels this is driving me nuts this bug.

 

I added a bug report for this, but included my entire project this time.

I wanted to check in and see if there are any thoughts on this? Still an issue for me each day working.
Thanks
