I'll start off with what I do know. You can paint your water at varying depths, and then come back and paint over the area with any selected nttXXXX or wnttXXXX .bmp, to simulate underwater sand, coral reefs, etc.
Has anyone figured out Settings->Terrain Type Settings->Change Ocean color/River color? I've been messing with it and it seems to do nothing, no matter what color I set it at.
What is the waterc.bmp used for? It's supposed to be for water color, but it is a B&W grayscale.bmp. Changing the shade had no effect on my test map.
According to the TE readme, you should be able to change the base ocean color for the entire terrain. Has anyone gotten that to work. I've tried the above steps, plus tried a new ntt0000 & wntt0000 .bmps. Neither worked, the ocean color seems to stay the default no matter what I try.
Anyone?
