I initially used a 2048x2048 background image that just covers the track and a short distance beyond. Realising that the terrain needs to extend further beyond the track edge, I added a second image (4096x2048) covering more area so it's got fewer pixels per sq meter (yeah, that's real fiddly to get two images to line up!).
Unfortunately, when I pulled the terrain polygons, BTB blending tiled the original background image rather than grabbing the second image. Do I have to use only one image for the blending?
