Would this save any work from the Raster Managers: render 2 landscape
models, one on each size of a clipping plane so that you cannot see the
other. One Model has a texture of only 256x256, the other maximum texture
resolution or clip-mapped, then render the smaller texture scene full
screen, render a portion of the other (high-res), from the same point of
view (offset to the other landscape) in a small window?
It's kind-of bulky on the polygon count, but would that type of rendering
save any work from the raster-managers? I'm lucky, I haven't had to worry
about overworking RMs, but this question started me thinking about it....
