Hi Christophe, Is the normal discontinuity only apparent along one longitudinal split? What happens when you zoom in?
I presume the normal discontinuity is along the boundary where the longitude goes from -180 to 180. The is code to equalize normals across boundaries between tiles, but don't remember any code that wraps around the the equalization so this might well be the source of the issue. As for fixing it, well you all have the source code... to me this is rather a minor issue in the greater scheme of things. When viewing the texture model a small discontinuity in the normal is hardly noticeable. Robert.
