Airport names in FSX

Most airports in the US have the name written in large white letters on one of the runways.I have always used FSSC to reproduce this by placing a DXT3 file with an Alpha channel in the appropriate spot as a Background Image and checked the "Visible in FS" box. (they have to be 512 x 512 1024 x 512 etc)Amazingly the objects I created (first in FS2002 then moved to FS2004) still work fine in FSX (even with ground scenery shadows on!)But I was wondering if there is another program these days that can achieve the same thing. I have used resample.exe to place much larger polygons with transparency but that seems a bit cumbersome...Any ideas?Geoff
