Thank you SO much man !
That's the best help I've gotten yet, by FAR !
Here's what's already happened in the map:
-I've added glass top dividers to the library, as well as the book beeper things.
-The courtyard got some benches & structural canopies over the doors.
-The Hall Of Mirrors Effect in the blinds has been dealt with now too.
Now, on to what you've mentioned:
- Stairwell shading is odd, but not awful. I might just live with it.
What was the problem with the railing tex/ lighting ?
I can't tell cuz the pic is really dark.
-I win the $100.oo !!!
All I need to do is slide the ladder up, through a ceiling tile ! I win !
-I absolutely LOVE the idea for the b-ball court !
The sidewalk around it & grass & trees are definately going to be added.
Also the door idea is brilliant !
It'll lead through a sports room/lock-up and back into the main hall.
I may add a fire escape there as well.
-I'll have to revamp the area by the dark pictures, to include a front foyer, with a set of front doors, etc.
Also very good inspiration.
If that happens, I may be able to open up the doors to the courtyard on that side.
-The library may get access through the back corners of the top floor, leading to the second floor hallways.
R_speeds are pushing it in there already, so we'll see.
Still a great idea though.
-R_speeds are the reason I cannot open the door or the windows in there though & also why the blinds cannot be made drawable.
-Classrooms may be pushing it, in fact, adding anything more at this point may be pushing it.
I'm already using almost every trick I've ever read about to make this map run after each compile !

It's HUGE ! 16Mb already !
Thanks again, man !
If anyone needs me ... I'll probably be mapping.

Cheers !
p.s. Doors ARE ugly ... will change.
