Not sure what you mean here, but I'm comparing 2 identical shaders
except one uses a loop and the other doesn't. The results are
_exactly_ the same if I change the index in the loop to a hardcoded 0
instead of using 'i'. Once I index gl_LightSource with a variable, I
encounter the previously described problem. So, I'm pretty sure I've
eliminated any possibility of my code being the issue.
thanks,
wes
