Ok, so I''ve created a sphere using gluSphere and I remembered to set the auto-texture co-ordinate generation on the ortho I used to create it. 1)How do I now map the texture to the sphere? 2)How do I make the sphere a light source? - I''m aiming for a ''sun'' effect here, is this some trick with using the projection matrix or is there a way to make an object into a lightsource? A friend of mine sent me frankly scary code for texturing a sphere that involved creating the sphere using triangles and mapping the texture onto that, whilst this works I''d prefer to know if there is a way to map onto the gluSphere. Maybe this would be a decent mini-tutorial? All help greatly appreciated. MrChris
