what do you mean by numpad - and +, if i hit those keys no pallete shows up for me. or do i have to open the pallette by enter and use - and +, but how does that change the color from the water?

watch what i did in the video :O

but alex i watched it over and over again but still, i don't get it. can you make a more clear tutorial please. the only thing you said is, let me make the water blue fast. and you didn't say how you did that, but what you did after that wasn't very clear too. but after that you created and deleted spheres. that was clear. please make it more clear, and say with everything you do, how you do it. so if you say, i make the water blue now real quick, you must say how and wich keys. please tell me. how did you do that?
