Hey hey people, I’ve got a wisdom tooth erupting badly and it impedes my reasoning.
I made a material that takes the vector and color of a lamp and uses it to create some kind of faux lens flare. I slapped it on a plane, sent it to an overlay scene, everything works as intended. Now the problem is I had to duplicate a sun lamp in order for the node to get any info, and it’s really killing my framerate.
So, can I do it without the nodes? Getting the lamp’s color is simple enough, but I also need the dot product of the plane’s normal and light direction so the lens brightens up when you look at the sun.
Any ideas?
