I've noticed that even if I have nospecular on a big light, there's still an awful much of fresnel reflections going on. I was going to reopen http://bugs.thedarkm...iew.php?id=4292 but after double checking the test map I uploaded back in '16 I see that no, the nospecular argument actually does work. It's the default specular you get with Enhanced Interaction Shader. Disabling that fixes the issue.
I definitely remember the fresnel not being as strong as it is now, can somebody (thinking either nbohr or duzenko) check if the default values in the shader have been altered or otherwise messed up?
