ok that is pretty awesome, and it affects everything or just some parts of the game?
well in areas overloaded with actors it will flicker the effects(like at death mountain for example),but that only happens in laggy situations. If you combine em you get different colors. Just play with em and you'll see what I mean. I had a yellow glow before. Im not sure how I got it though.
The only explanation I have as to why these glow codes are even in the game is possibly for when the sages or when you get a stone they tend to wanna make a glowing sphere of a certain color and I guess Nintendo originally wanted to add glows, but couldn't load them? This might as well be beta leftovers if you think about it. (IE beta quest1, Ice cavern BETA the water turns red and in the other room with the puzzle its sharp light blue glow in every piece of texture.)
