I was playing around with the built-in webGL effects, notably the water one and some color changing ones, and I had some problem using some of them, like I could not understand their exact purpose or how to use them effectively (the ones with no parameters being pretty hard for me to wrap my head around, like "Burn"), that could be because I am not a native english speaker combined with the fact I am kind of stupid sometimes, but I just wanted to ask if other people had troubles with understanding some effects.
