Water System Issues (!?) - Help Requested.

Hello Knowledgeable Unreal Engine Users, I am a complete beginner and I am looking for advice on how to use the water system in Unreal Engine 5. - Namely, I created a landmass with an ocean (from following a tutorial online) and finally figured out how not to drown my landmass (by changing the blend mode so my ocean stopped snapping to a different point), only to have it drowned by each consecutive body of water that I try to add - whether river or lake. Basically, it’s somehow matching the water height to the ocean height and deciding that the ocean has to rise to “work” - which is not at all what I want. I want higher-level lakes and rivers (note that the depth of such seems irrelevant if the altitude is different… ?) that taper down or have waterfalls into the ocean… I do not want my ocean level to rise and am unsure of why the system is created to do this… since I think most people would find this unwanted and extremely frustrating. Please let me know what I am doing wrong or if there is any way to fix this; I find drawing the elements onto my map easy enough… P.S. The images show the difference between the check box “affects landscape”… as you can see my land is getting completely flooded.

Thank you!


Short update, I did find where I can turn off that the height map is affected under Landscape_WaterbrushManagement - so then I can click “affects landscape” on all of the elements, but it doesn’t seem to work / change anything. I have the problem where my water is basically hovering over my landscape, so if I “jump in”, I am in a hollow space with water on the sides and above me… not at all what it is supposed to be doing. From the outside it looks like a wall of water towering over me… unless I am very careful to place it, but even then it is not properly reacting to my landscape on the edges (looks bubbled or doesn’t touch right) and is hollow as described. Additionally, I want to hide / remove the base of my landscape, which I created with unreal (add landscape, then modify with modeling brushes) - because my ocean floor is too flat and much too shallow for where I intended the coastal line to sit… I have no idea how to fix this, but I really want to and would be much appreciative if anyone knows how. Thank you!

I found my solutions, so I am marking this as resolved.
