Here's a glass floor for all those that want one. The one problem is that is completely invisible (I hear you cry "well, it's glass, of course it's invisible!") but what I'm trying to achieve is to have it looking like the glass in the windows you can shoot (with the emblem in the center)
But I can't seem too! Anyway, it might be a good idea to put some sort of hand rail either side of the glass floor if you're making a bridge / walkway.
Here's the segment, just unzip it and put it in the segments folder of the main program.

If anyone can have the glass show that would be great.
