I found this simple tutorial on how to make a water texture. I quite like the look of the texture for the theme of the game I'm working on, but I can't figure out how to recreate it. I don't have the gradient that is referred to and there aren't attachments on the page. It looks like the site isn't used any more. I tried as many variations as I could, but I get way too many "waves" on the lava texture that are too thin and I can't find a gradient that works well. Does anyone have any suggestions on how to get the texture/gradient?
Here are the instructions given:
Start with new image of desired dimensions
Go through menus Script-Fu > Render > Lava, a new window will appear, select gradient named Horizon 2 (if you do not have this gradient in list, then download attached file, I do not remember from where I downloaded this file, credit goes to respective author. And if you do not know how to bring this gradient in list, see FAQs).
