Yeah that is right - that is because you don't inherit the bitmap in your model. I'm not sure, but A6 creates the mipmapchain automatically when you load the model. If it is not so you can otherwise save your texture as DDS file. There you can precalculate the mipmaps so that A6 doesnt spend time on it (faster loading), plus, even with the mipmaps inherited, the DDS file will be surely smaller than your original texture file.

Plus whats the best way to blend two sections of road (2 models) together.
I don't understand this question. When you've done a big model of your road and you've chunked it, the several chunks fit perfectly together. In the following picture I made a quick road model.. the red and green part display the 2 chunks for instance. You seperate them and later in WED you stitch them together... voilá!
