Thanks Cinole, that fixed it for me. Only commenting on this old thread because the OP and others may be affected by something else. The Water Body Ocean has a setting “Affects Landscape.” When that’s turned on, you modify your water depth with the “Channel Depth” setting. However - doing it this way, you will get those odd rises on the corner of your landscape similar to your screenshot, as it is channeled from the center, and compensates outwards. What worked for me for that, is to just turn off “Affects Landscape” altogether, and then modify the landscape’s Z coordinate as needed.
