I have made a vr game for android. More specific for use with meta quest 3. I started out in unreal 5.3.2. It works great and packages just fine there. But i recently upgraded the project to unreal 5.4.1 and i have encountered a problem. A lot of (but not all) my shaders are white. No shadows either. Just a solid white in the packaged game. Previewing it in the editor, as if it was running on android gives the same result. There are some exceptions like the ground and some objects that doesnt have static lighting - they look normal. (I use baked lighting for my project btw). I discovered that switching to deffered renderer «fixed» it, but forward renderer is my preffered renderer. Why is this happening? I am stuck. Any help would be greatly appreciated.
same problem here, although it was running and i guess i must have changed some of the render settings at some point 
- if i figure out what it was i update 
the problem does not depend on the render settings or shaders. It seemed to be linked to a bad map-built. Although i couldnt figure out what exactly it caused: it was depending on a particular map. Recreating this map helped in my case and might save some effort … Delete built file of map could work as well
