Emission baked Black, lightmap very blocky?

Hello, I’ve been messing about with Unitys Baked Lightning, and I’ve come across a problem.

All the emission lights look fine and bake fine but i also have a plane with the same emission material, but when I set it to static the light emmiting from it gets baked but its very blocky and the plane itself is now black (its lightmapped to black),
ofc if I don’t set it to static its fine but it doesn’t cast light.

I don’t know why its so blocky, and I need it to not be black when baked

Thank you I’m still a noob with unity.

Update: I have managed to make it so that the emission isn’t black anymore, i don’t know how.
However the entire lightmap is very blocky, I’ve increased the lightmap res to 4K via script, and my texels to unit is 400, and I’ve switched to Deffered rendering path, but its still the same,
Im working in Unity 5.1.1

I did eventually solve all this,
my scene was scale 2 instead of 1 , I didn’t realize that scale in unity mattered and that one unit is one meter, previously I’ve scaled the scene to match the FPS controller provided by unity.

Its still not perfect, there is some squareing going on the floor at the door thats creeked opened,
so I still need some help with that
