you need to also use 3d effect addon, 3d effect addon has a parameter to enable. works best on low poly/large poly objects
is that the mikal_frag_light-8-2.8.0.c3addon? what parameter is it? I have tried toggling the booleans but I don't notice anything.
yes that is it, it doesn't have an effect unless large polys at low texture rez at angle more parallel to camera
