3rd party developers can’t help here. We do not have the ability to make transparent ocean or lake polys, which would let the aerial imagery show through. A good example is Fakahina (NTKH). WU13 added the missing aerial imagery of the lagoon, and then covered it up with a ‘lake’ poly. We can exclude the lake poly to see the aerial and change it to land. But adding any type of water poly back in now covers up the lagoon with the opaque water shader of it’s type.
