How do I use IES lighting with a sphere? ( Hey,everyone! I'm in a bit of a pickle. I created a wonderful IES node setup thanks to an amazing tutorial and it works with planes and circles. However,I'm having trouble with one mesh in particular,the sphere. When I use a sphere to try and light my scene,its curvature the light scatters incorrectly. Could someone please tell me what can I do to fix this dilemma?

Node Setup
Thanks to a little advice from my commentor,Jaroslav Jerryno Novotny,I figured it out. For the first Mapping node connected to the Geometry Normal socket,change the Z-axis scale from 1.000 to 0.000. I know you're facepalming right now because this question was stupid and it had an easy answer,but c'est la vie.
