If you just want to do the colors for the water as a visualization aid in World Machine, you can definitely do that! Again, it would only really be helpful as a visualization thing, you wouldn’t want to export the terrain, but if your oceans are generated by a Coastal Erosion
and/or Create Water
device, you can pipe the water output into an Unpack from Composite Type
device, grab the “Water Surface” output for the final heightmap, use whatever method works best for you to isolate the water area (output masks or combinations thereof work, or, in a worst case scenario, you can always get the Absolute Difference of the water surface output and the actual terrain), and adjust colors in different areas with masks and colorizers as you would any other highly locational coloring. Here’s just a quick and dirty example using an old project of mine:
Obviously, it can be refined to look better, this was just slapping some colors down, but it can definitely be useful if you’re looking to visualize! Since you’re using the Water Surface output, you likely wouldn’t want to use the resulting heightmap anywhere else, but it’s great for visualization!
