Replace ocean with color or texture
Hello, I’m rather new to GM.
I have georeferenced aerial photos that contains a lot of ocean. I also have height data for the same areas. Is it possible to replace all photos below a threshold (say 0.1 meters) with a generic color or tiled texture?
We are using the data in a game engine where we stream in the texture tiles based on camera location, and we also have underwater seabed which currently is colored with ocean photos. I would like to replace the photos of the ocean with a generic color. Because of the varying color of the ocean in the photos I can’t just select based on color, which is why I was hoping to use the heightdata as a “mask”.
Hope this makes sense, any help is appreciated.

Try using the create single contour feature with your height data and select to 'create area features' using 0 or 0.1 as an elevation. This should produce a 'mask' like feature.

How would I go about actually applying this result as a "mask"?
