I completely lose it when the tutorial gets to the hills mountains reef ocean layer, not sure if I am supposed to deselect at some point before hitting it with filters? Also, it's very confusing to switch back and forth between duplicate and copy, especially when I keep getting "background copy" layers, and the tutorial is getting "base copy" layers.

Arg, the results look sweet, but it gets too confusing for me to understand when something goes wrong, was it me, or was it not understanding what he wanted when.

ps, plus,render > lighting effects filter seems to have lost a few options between the version the tutorial uses and the one I use.
