Hi All, we are having an issue with lightmaps for a VR project that is deployed on Quest standalone (Android). At runtime, when moving the view direction, the lightmaps kind of “switch” to a weird state, as if they were applied in negative - see animation and single frames attached. We are only baking static lights. Any hints on what might be the cause?

We have other projects with the same setup and they work just fine, and also the Android/vulkan rendering preview in Editor does not show the issue either, so we are kind of lost…

The project is based on Unreal 5.6.1
