I'm going to try flattening the poles of the sphere, so that they are in-line with the points on the next 'layer' down, and see if that cut outs the 'lines' effect. The POF is already too many polys to load into Modelview (see latest model).
I could do the poles as a planar mapped seperate material, but it would be a pain getting the scaling right on the images.
As for Seamless, the 'seams' are created by the polys at the pole of the skybox, yes it is possible to fix this with gradient fills etc, and when I have the time I will, but right now I'm just bashing ideas around
