Hi guys,

I recently updated to 4.19, therefore I cloned my project and run with 4.19. Now, in a specific area on this project I’m experiencing this weird problem:

- several meshes became completely black
- deleting all spheres reflection captures from that area “solves” the problem (meaning that I can see the materials but of course without proper reflections).
- deleting all spheres ref cap from the area and adding just one causes the objects that are close to it to became black.
- WHAT I SEE IN VR PREVIEW DOES NOT CORRESPOND TO WHAT IS SEE IN EDITOR (!?)

How can this be? Huge gratitude to who might help me (and to who tries of course) 🙂

You have to build your reflections now under the build settings.
