Additional Notes

These bugs weren’t happening before the latest update. These bugs don’t appear in PC. They also don’t appear when emulating Gen9 console in the UEFN editor.

Just a follow up, after an afternoon of testing:

this can be reproduced in UEFN by using the Gen8 preview
in a fresh file drop a basic cube and rectangle light
drop a day sequence device and disable all other light.
the banding occurs as you position the cube beneath the light

It’s not the mesh or the material. It doesn’t happen from point lights.
