Cool thanks. Is there anyway to change the opacity of the starting ocean water or otherwise manipulate it aside from just the depth/height?
1. be carefull with textures, you can use a lot of them on your map, but as far as I know you shouldn't use more than 8 different textures on a single terraintile because that might break the texturing and you'd have to retexture the whole map.
happened to me a while back, not 100% sure about that tho, but better safe than sorry...
2. The Water of the ocean can be altered by selecting the terrain tab in the rollup-bar (where the layer painter is) and hit the "environment"-button.
there's a list of parameters which can be used to change a couple of global things on your map, including parameters for the oceans texture, fogcolor, fogdensity, waveheight/-speed/-direction, etc.
Supposedly you can change the default ocean opacity in the environments subsection of the rollup bar but my environments subsection is totally empty of options. The variability between what's in the tutorials and what's on my computer is driving me bonkers. It's so different. Any ideas on how I can get my environments back? This ocean is far too dark for my liking.
I suppose it's obvious how to change the color of the ocean, if it's too dark/bright use the fogdensity, and fogcolormultiplier to adjust it.
for the density I recommend to use values between 1 and 0, same goes for the colormultiplier since higher values will make the water look glowy, and unable to see anything for the density.
I wonder why ppl instantly want to mess around with the paks in order to make things worse...

You shouldn't touch any of them unless you know what you're doing...
