Well, that will be very much appreciated
FYI, for floors, even 512*512 can look good in UT because you can blend other textures to make a unique looking materials. Most UT3 stock textures & even many UDK floor textures use a 512x512 resolution. You just have to know the Material Editor a bit.
I'm looking for a dark, square like floor texture because the map I'm building will use a sci-fi, techy theme & yours fir perfectly
I'll look forward your next great textures pack
