ive written a glut app that utilizes all 8 opengl lights for animated scenes… except the only one that seems to work in GL_LIGHT0. all others have no effect on the display of the scene(under linux, that is).
the same app compiled and run on SGI octane works fine - all lights functioning.
is there something im neglecting to do? or is the linux/nvidia/mesa implementation of opengl just lacking in this feature?
im running kernel 2.4.13 on an i686 athlon
redhat 7.1
nvidia 2313 libs, XFree864.2.0

The lights work fine. Maybe you didn’t enable each light? – Don’t know why this would work with an octane, and not a linux box.
yep, it turns out i was crazy.
the lights were being initialized to exponent 0.0 and cutoff 0.0.
perhaps the SGI impl. recognizes these values and replaces them with more sensible ones? kind of a stretch…
