Broken (missing) scene lighting?

Far too often, on multiple projects, the Android (for Oculus Quest) builds created by UCB are broken with regard to the scene lighting. They often appear far too dark - almost as if the baked lighting isn't included, even though the logs show it being imported during the build process. Local builds do not exhibit this issue.

There's a mix of OpenGLES3 and Vulkan across the projects, so it doesn't appear to be specific to Vulkan, which I first suspected. I believe that most use Linear color space and sRGB.

Automatic lightmap baking is disabled. UCB configs are set to use the latest 2019.x for all current projects, although UCB sometimes lags by a version (or two) - we're currently on the same 2019.4.29f1.

Any thoughts on where to look to figure out why it's happening, and any potential fix? What's a 'typical' setup?

Thanks in advance,

I'm currently also experiencing an issue like this. My team is on unity 2020.8.3f1 and the baked lighting works consistently everywhere except the mobile builds coming from UCB. The dynamic scene objects' shadows are far too dark, as if realtime indirect baked lighting isn't being applied. I want to say that the cause is that we're using additive scene loading and manually setting lightmap textures in between loads, but the fact that the realtime lighting works when I build locally with my macbook does seem to indicate the problem is at least partially happening within Cloud Build.

 

@ollieblanks @rajivrao Any thoughts on this?

 

Hey @gjf, if you're still working on this. I recently made a few changes to my project and the lighting seems to be working, at least for now. I'm not sure which one did the trick.

• Upgraded the editor from 2020.3.8f1 to 2020.3.15f2
• Changed light baking mode from Shadowmask to Baked Indirect
• Performed a light bake on my main/persistent scene. In hindsight I should have done this from the beginning, but since my main scene is entirely overlay UI and has no 3d I didn't think it was necessary.

Good luck with your project!

 

Thanks, much appreciated. I'll give it a try and let you know how it works out.

 

Sadly, the same issues for me...

 

@rajivrao Thanks for the reply.

I haven't submitted a support ticket because I haven't had time to create a sample project showing just the issue, rather than needing to share the entire project.

The build is for the Oculus Quest/2, so it's very much a VR headset! Cloud builds work with the exception of the lighting issue. From your comment about the device, is UCB not recommended for VR headsets?

Thanks in advance,
g.

 

Thanks; it seems to be just the lighting that's messed up, so hopefully not a million miles away...

 

Hi @rajivrao

Are you able to provide a broad timeline for this fix, or perhaps a temporary workaround besides building locally? Cloud Build would be an incredibly important service for us to leverage and since we've already paid for a license that does expire after a specific date, it would be helpful to know when it becomes a viable option (whether that's in the near future or distant).

I seem to have tried changing just about every suggested rendering & lighting option I can find, but nothing has done the trick yet.

Thanks!
