tips to make huge parking lots?

[salf]

Im wondering if you guys have tips to make huge parking lots?

 

Im making one for a mall project, and i thought about making a "mask" (jpg image black/white) with all the parking spaces, arrows, letters, etc and mix 2 materials, white for the paintings and asphalt, but this is prety hard to do, and then to fit properly in the model.

 

Any ideas?

why is it hard?

 

just draw your parking lot in autocad in a shape exact to that of the model, transfer it to PS, add pavement, arrows, lines, whatever, and youre done...if not working with autocad (which makes drawing the lines s lot easier), then, make a "top view" render and take that to PS...then draw your map and give that material to the object...
