Forging Outside Maps & Lightmapping

So, I am currently Forging a map outside of The Rig. The problem is the lightmap, or rather, lack of it. It’s causing some really weird shadows (see attached), and light baking and chromas seem to do nothing. I tried creating a fake sun to force a lightmap, but when I tried light baking it in, it just shone right through as if the blocks were dynamic.

If anyone has some info on whether it’s possible to force a lightmap or not, that would be fantastic.
