Error building Player: Couldn't copy player GI data for scene

Hello, I'm having a very strange build error that is making the builds fail with cloud build. The log is

[Unity] Error building Player: Couldn't copy player GI data for scene 'Assets/Scenes/GameScene3.unity' into data folder 'level3'
[Unity] Player export failed. Reason: Error building Player: Couldn't copy player GI data for scene 'Assets/Scenes/GameScene3.unity' into data folder 'level3'

Any idea what is causing this? I doesn't have any folder named level3

 

Same error after upgrade to Unity 5.2.1.

 

I tried making a build, then running the game trough Xcode and it worked without problems. I'm a little bit confused if this is a thing from the server or my project.

Someone from Unity that can give us a hand please?

 

Getting the same issue, on 5.2.1 and 5.2.1p1 - worked fine on 5.1/5.2.0

Error building Player: Couldn't copy player GI data for scene X into data folder 'archive:/X' etc

Bit of a showstopper as we need a bunch of fixes from 5.2.1

 

Any news? =( This is a real slowdown for our game since we have to do a manual build and use testflight to send the build

 

Submitted a bug last week - hoping it gets fixed for the next update but no idea where the issue is in the priority...

 

Same issue.

 

Someone from Unity?

 

Re-baking my one light-map fixed it for me, but clearly this doesn't scale well to people with large projects.

 

Having the same issue, too which prevents us from building our project.
Re-baking every single scene would be a really bitter pill to swallow. Is there no other way to have the affected projects build properly?
It would take several nights to re-bake all of our scenes and to be able to build again.
We're currently in Early Access with update releases planned every two weeks. The brute force way of re-baking the whole project would have a major impact on our planned time frame.
So an official statement or workaround way to solve this issue would be really appreciated.

 

Actually that didn't solve the issue for me. I cleaned all the GI Cache from Unity, and rebaked every single scene. Same problem happening when I tried to make a build in the cloud

 

Thanks
I also created a repro case with the number 732324 providing a small scene with the respective errors.
For us we decided to downgrade back to 5.1 for now.

 

Did you solve the problem with 5.1? If so, I will do the same. This bug is very frustrating

 

Yes, with 5.1 everything works fine. I'm gonna check on the newest patch release from yesterday (5.2.1p2) to see if everything works fine now.

 

Thank you!!

 

any luck?

 

Nope, sadly still present for us in the latest 5.2 patch release

 

Mmm, interesting. I erased all the GI Cache from the Unity Preferences panel, and rebaked every scene in my project. However same result . Am I missing something?

 

It's a bit weird, we're working on a couple of different machines and never had that kind of issue in 5.1. Does that mean the data was corrupted on each machine in the same way? During our development in 5.1 we cleared the GI cache several times on a couple ofthose machines, still we didn't have the problem.
So was the data continually corrupted, no matter how much we clear the cache?

I'm a bit afraid of upgrading to 5.2 if that means we have to re-build the lighting in every single level. This would cost us a couple of nights of bake time that we actually need for baking the new content.

 

I just checked our project and (judging from the file size) it looks like among the 160 snapshots we have in the project only 9 of them are in a non-corrupted state. All of the others don't even reach 1 MB in size.
I'll look into the issue for our specific case and see if clearing the cache will produce either produce the build error or give a clean snapshot.
Gonna post the results here for everyone to refer to and provide a repro-case if cleaning the cache doesn't help.

 

Sadly after clearing the cache I didn't have any progress on this problem. Building still works despite the clean cache, the newly created snapshots still only have several KBs and I submitted a bug report on this issue with the number 734395.
Absolutely no idea what we might be doing wrong since we do have a couple of working snapshots (between over 150 corrupted ones).
I also don't understand why it's only a problem in 5.2. We can still properly build our project in 5.1 even if we clear the cache. Maybe the warning "GI output for inputsystem: [number] is missing." is related to this issue?

 

Yes, the snapshot is bigger and seems to work correctly. It'll need some time to completely confirm it's working (since we have to re-bake the whole project) but after testing in a single level the warning for this level's snapshot disappeared. Thanks you

 

I'm still having the issue. I cleared the GI cache, and baked again the lights. Am I missing something?

 

I'm using 5.2.0f3

 

All fixed this end, we just had to rebuild as Joachim suggested. We're using 5.2.1p4

 

I tried to bake some more levels in 5.2.1p4. At first glance the issue seems to be solved and we can build the project. The lightmap snapshot still is very small though (110 kb in a scene with several dozen lightmaps).
Is upgrading to 5.2 a good choice anyway or is there still something wrong with such a small snapshot?

 

I was able to get around this error, by copying over all the items in the broken scene into a fresh scene (in Unity 5.2.2). Clearing the cache and rebaking wasn't working for me.

 

We're been using

//
We've been using 5.2.2f1 and it has been working pretty well for us.

 

has this been fixed?

 

Fixed and broken again
