Bug: PBR Shader becoming darker and lighter depending on where I am standing.

[JackRHainsworth]

Describe the bug

When using a PBR material, the reflections (even without an envmap) become darker and lighter depending on where in the level I am looking at them from. This is most noticeable when moving through portals and seeing the color darken quickly.
