I don’t think the problem is wholly to do with the mesh. I’ve tried rolling back various mesh and vector files to previous versions as I did with my spike fix but the glitch persists. I think the problem lies with the algorithm for dealing with shoreline vectors ie it’s hard coded. If you look at the screenshots below you can clearly see that shorelines are now being abruptly clipped to produce ugly cliffs everywhere. It’s these cliffs that are resulting in the climbing water effect.
The first screenshot shows how the coast used to look in earlier versions of the sim. Looks fairly good and natural:
The second screenshot shows the same coast has now been turned into poorly textured cliffs:
And from a distance the same cliffs produce the climbing water effect:
The only thing you can really do for now to reduce the ugliness is bump up your terrain LOD in UserCfg.opt. Anything above 5.0 though is diminishing returns.
