Every time I build lighting, it removes static shadows being cast by my tree mesh. I don’t know if my terrain is too large (scaled to 2k) or if there’s another issue. The image below represents the changes, top half of the image is before lighting is built, bottom half is after lighting is built. The tree bark is self shading decently, but it’s not casting a shadow and neither are the leaves.

Try increasing your lightmap resolution for the landscape.
The, “Static Lighting Resolution?” It was defaulted at 1, what should I raise it to?
When it’s a landscape, dont go over a resolution of 6 
Good to know, and thank you! For some reason changing the directional light from stationary to moveable fixed shadows. On to the next issue 
Thanks again!
stationary -> static + dynamic light
moveable -> dynamic (no light building)
