What are your lighting and shadowing settings? Baked lighting or “no precomputed lighting?” Ray tracing?
What’s the material like?
What kind of reflection capture do you use? What’s the resolution?
What Ambient Occlusion settings do you use?
Any other post processing or camera settings?

-I tried checking (force no precomputed) on and off, and it seems that the issue in dynamic and raytraced shadows and ssr…((now i choose force no precomputed))…
-the material is car paint from the default project…
-one big sphere reflection capture…
-reflection resolution == 2048 ((epic settings))…
-override lightmass res = 1024…
