Unreal Water Body Ocean_ Flattens my Heightmap Terrain

Hello all, I have been experimenting with the Water Body Ocean to add to my terrain that has been extracted from a Height Map, and is partitioned, however every-time I attempt to add this Water Body Ocean, it just flattens out my terrain leaving a flat terrain.

I have a landscape that was generated via a height-map and the terrain features a large bay but also opens out to the sea, however every time I try to add this Water, it just flattens the entire landscape to a Flat plane. If I delete this water out of my scene the landscape returns.

Is there any way that the Ocean can be used with a Height-map terrain?
This is not an island though. The terrain is over 8 km in size. I have had some success with the Water Body Custom though have not customized it other than enabling the Gerstner Waves, though I am not sure will it be possible to have the Ocean type waves for the ocean area and then the bay would the have the slightly gentler waves, with waves shallowing out with foam on the beaches.
is this possible with the Custom or is this only in the Ocean when the Ocean currently does not work with the Height-map and Partitioned terrain, or is there some other setting that I am not aware of to stop it flattening my landscape?

Please let me know of anything I could do or if it is that suitable or what the issue may be that could be causing it to flatten my landscape every time I attempt to drag in the Water Body Ocean.

Thanks Regards

I run into the same issue and would be interessted in an solution too.

Having the same issue, I mean I could just create a new map that follow some tutorial, but it’s weird that all these issues exist - how can it be that adding something like body of water would destroy all that you’ve built so far. What’s more scary is that it seems that no one has answers for these issues.

I am having the same issue, anyone have a fix?

You can try to use “max” instead of “alpha blend” in the blending mode. You’ll still have to deal with the spline (like hide it somewhere) but it won’t flatten the terrain that’s not in between the spline

Try selecting your landscape in the outliner, going to details, unchecking the Enable Edit Layers, and then placing your Water Body Ocean?

Unclick “Affects Landscape” under WaterBody

I actually created a 2nd landscape and made the material ocean and that worked for me.

Thank you. This is the actual answer. It worked and helped me.

Go to the water body details, and under terrain youll find curve settings and water heightmap settings. I found changing the falloff angle to a larger one worked for deflatening my landscape. You can also fidle around with the curve settings to see if you like anything else. This means the waterbody still interacts with the terrain, and you dont need to make a different landscape, and set its material to ocean (which to what I can see from the photo in one of the replys, doesnt have waterbody physics. If im mistaken about this please correct me). Hopefully that helps.
