I have no clear view on the impact of this, but it sure looks like an interresting idea. It bascally redices CLOD to 'split' LOD. > > Yes, I think that's a very good idea; in fact, if you wanted to go to > three layers, the furthest one could be simply untextured, coloured > polys (that's what you'd see from 120,000ft, for example).

I was thinking about mixing the most common used color and the avarage color. I haven't tested this but looks like a good start. I realy should try it some time.
