Hi, i''ve been trying to manipulate the direction of a light source using glLightfv( GL_LIGHT1, GL_SPOT_DIRECTION, LightDirection); and guess what ... nothing happened. *g* Is there anything i could have done wrong? I mean, i can''t imagine that its hard to change the direction of a light .. Second question: What do i have to make GL_SPOT_CUTOFF work for one textured Triangle (or quad or whatever) (or do i have to split the Triangle? ) Thanks, Dave

If you have only one triangle, spot lights aren''t going to show up very well, the triangle will either be lit, or it won''t. Make a sphere or torus or something, then you can see it.
