Thanks for the reply. I concure with much of your thinking here. I've wondered whether some tile groups have priority over others, although there always seems to be exceptions to perceived rule. I've also wondered how they are made. My guess is that they are 256x128 images reduced in size to 256x32 and then placed in a line making up the 32x2048 bitmap.
I'm going to have a play with a set of tiles in the next fews days and see what happens. There's guy in germany that's done a bit of this too, so I'll try and contact him. I'd realy like to get a set of 'crop' tiles that I've made sit clearly and consistently on top some 'field' tiles. Also, the same technique is being used in FSX (as per the demo anyone can see). Unfortunelty, this does not do the new 1024* tiles justice. The belnding looks realy rough against such nice higher res bitmaps. I've asked the FS people to provide an SDK on this, so maybe we'll get better info in the near future.
