Haven't worked on this map again since I created, due to working I'm doing on Agrobathe my primary project. But I did find out the reason for the lines. They come from a lighting texture included as part of the 3D effect->Bevel tool. The texture basically has 4 squares and texture on each square. The lines are from the lines going in a cross in the center of the texture. Ugh.. wish I had known about that before I did the bevel. At least now I know it's there in Corel Photo-Paint. Others beware of this when using Effect Tools->3D->Bevel.
