It's a copy of the detention block in this case. I use whicever is closest to the plain room segment I'm after so no need to re-copy new x files --might as well use the models already in FPSC. (I forgot which one I used).
In the next update (the one I'm using now) there are some original models and I get rid of superflous lines because it will add more flexability to how the segment looks. Plus you'll get to edit the material type so different bullet holes and walking sounds. Right now you can make a grass segment but it sounds like you're walking on --the scifi detention block floor! I'm workin' on it.
Thanks everyone who got Magic FPS so far! It's already catching up to Grave Matter and that's only in 3 days! There's no more question about lack of interest so I'm moving forward with the most ambitious updates I can figure out!
