Darn simple solution, 3 layer floor, not very cost effective, any thing to get away from the annoying patterns, and entities have no problem walking on them I am going to add another additional layer for floor vents.
I have abandoned the underneath floor segments, as it turns out with the shapes of the segments and floor segments would make it a bit complex and tiresome and not very user friendly, layering floors quick and easy solution, gets the job done and still looks surprisingly good, albeit that 3rd layer still irks me, will replace that soon, will have to replace that.
With the floor out of the way, I can look at adding MOAR entities....
Edit*
Excuse the quality

And the fraps stutter.
Floor in action, as well a wall divider, that really breaks up the level, and makes smaller rooms,......
