Lightmaps broken on Android

Hi,

I have posted the following issue in the 2019.3 beta forum since that is the version we are using, however on later thought it might fit better in this forum section.

Lightmapping issues on Android with LWRP

Setup - Unity 2019.3.0b8 on Windows 10 64bit - LWRP (Universal Render Pipeline) - Linear Color Space / OpenGL ES3.0 - Samsung Galaxy S7 Edge (Android 8.0.0) Hello folks, we are currently experimenting with baking lights onto prefabs in Unity using the script provided in this thread. https://discussions.unity.com/t/579773/6 While everything works fine in the Editor, the lightmap is utterly corrupted when deployed to an actual mobile device. Has anybody an idea why that is ? Editor …

Basically creating lightmaps looks great in the editor but they totally break when deployed onto a mobile device.
It seems to be a UV issue but I don’t know how to debug this at all.

In case people stumble upon the issue here, the discussion is being held in the thread above.

Do you have both Realtime GI and Baked GI enabled in your scene?

[Krasshirsch]

Yes, both were enabled. I already issued a bug report which has been successfully reproduced.
