I know all that but it doesn't work, I define my gluperspective on an older version where the lightning system was not enabled (i use glcolor3d, and glortho) and i just replace glortho by...

Here is an exemple of my init code for gluPerspective

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(45.0,1,0,10);
gluLookAt(0,0,0,0,0,-15,0,1,0);...
