[5-0EA] Weird Reflections and Lighting UE [5-0EA]

I’m working on a project but I’m running into some weird lighting issues and reflection issues. For my first issue it seems that my ground may not be reflecting on my model as you can see here


I looked and there is only black where my ground is on a reflective cube.

My other problem is in a space scene I have weird pixelated or dots all over my models. This isn’t messed up normals as I already checked that it also happens on default shapes like cubes…


As you can see here. If you have any info please LMK!
