Unreal 5.6 ShallowWaterRiver simulation nowhere near the WaterBodyRiver spline

Hey Everyone,
As you can see from the above screenshot the simulation seems to be simualting randomly about 15000 units in the negative Z axis from my actual Landscape. The actual WaterBody spline was conforming to the Landscape and i had no issues until I plugged the WaterBodyRiver under the source River Water Bodies under the water parameter group of ShallowWaterRiver.


when is turn off the use Capture checkbox the simulation seems to be aligned but this is not capturing any of the other collision objects under the Bottom Contour tags. I am using Landscape Level Partition system as well just for the context of troubleshooting and the water river body flows only within the visible partitions.

Is there a way to troubleshoot what might be the culprit here.

Thanks a ton for any support or help provided.

Just to say I had the same problem on the default open level, and found the same “solution”. But with anything but flat landscape it just flows way above instead. The resetting the 15000 Bottom contour Capture offset doesn’t seem to do anything either.

I check the code and found it use ActorBound to get landscape pivot, but in WP level ALandscape doesn’t have valid bound, so it got wrong; maybe just wait developer fix issue

Have the same issue here. Will this be fixed in the future?

It’s an undocumented “Rule” for using UE:
Don’t use landscapes.
If you use landscapes because you “Must”, DO NOT MOVE landscapes.
And - make sure that the landscapes are always square in size.

Once you move landscapes around, you start to get all sorts of issues (because the engine is basically the equivalent of what Twilight is to the English language by now, they keep on hiring incompetent developers, or canning the few who are competent I guess).
