Here's the indoor, 3-story building tutorial. Only cover doors and room. I fucked up a bit at the beginning b/c I wasn't used to the interface. I skipped cleaning up the mesh b/c I thought you would know how to do something like that. Just basic box rooms, if you want more, learn techniques, but this is just basics down seeing how you have trouble with EVERYTHING! About 14 min, I sounded sleepy b/c I was. Volume of voice is low so turn up yours. Sorry if you can't understand.
