It's mostly done. I had some issues with lighting but I just kept messing around with angles and rotated my sky so the sun lined up with it and eventually got something good.
The only issue now is that I discovered a magical hole into the side of the interior. Unfortunately I can't open up torque constructor and try and fix it because torque constructor magically decided it can't export the interior anymore (along with every other program) so I'm stuck with what I've got. There's a pretty easy solution around it though, I'm just going to model a box of nails to put over it.
I've going to blame this one on torque constructor, I don't think it's sketchup's fault.
There's a few of texturing issues as well. It's just a couple of 2x4s where the wood grain runs perpendicular to the direction it's supposed to, people probably won't notice. Unfortunately torque constructor is acting up so I can't do anything about it. I did go back and fix them but it doesn't really help when there's no way to export it. When I get this map released (within the next few days if not today) I'm going to reinstall constructor.
My next project won't be an unfinished building so there won't be millions of repeating 2x4s to texture (or break) so hopefully it will be a lot smoother.
EDIT: If someone wants to try exporting this themselves just send me a message.
