UDK now has better more-accurate… -

Your gloss map controls the tightness of the point lights, as well as the blur of the specular reflection cubemap,… -
Re: Why do we use specular instead of reflections?
actually i have worked on many games that use cube maps reflections for spec,and duffuse cubemaps for bounce lighting. in fact most deferred engines do this. it looks really nice and is better than the old school blinn spec. you dont have to render out separate cube maps because cubemaps have mips, if you want a rougher… -
Re: Why do we use specular instead of reflections?

So confused but feel I should really grasp what you guys are talking about lol XD. "actually i have worked on many games that use cube maps reflections for…
