So we're all having fun over Dutton! (a.k.a. the 'hunting grounds')
I've just dumped my Ayer's rock textures to Dropbox, will send you all link so you can see what I draped all across central australia. Due to its sheer size, I had to use 50megs of textures and of course the rez is not as high, a slightly larger area
. Make sure you take a tour out west to the Olgas. Use something fast though, like the Xbone or 3600. The colours are pretty close to the real thing, they call it 'Bulldust'.
