Sorry, I still seem to be having the same problem.
I downloaded the latest version following the help section and added it to both the demo and a blank project to test. In both cases, it just doesn't seem to work (load?). There's no error message and nothing happens or changes in the game. There's not even the 'Lighting Effects' option added to the option menu, as if the whole script just refuses to load into the game somehow? (like the script's not even there or were off, even though it's on)
