Well, I did steps 1, 2, and 3, but I can't agree with 4. (Average the normals for a smooth shade (Edit Polygons > Normals > Average Normals) If I do 1 - 3, the dark streaks go away. When I do, they come back. *5 minutes later* Ok. Now I am at the conclusion that all you need to do is Set Face To Normals. If I only do this, everything is fine. What is the purpose of steps 2 and 4?
