Hi there - my first time posting in here, been working on a game for a while that I’m really happy with and generally been able to solve any problems thus far, but one day I loaded it up to find that the river section had just randomly “dried up” (it’s still affecting the landscape but now the river water doesn’t flow down from the landscape it’s just sitting at the same height as the ocean) - the landscape and the river have both had their transform locked so I trust that it’s nothing to do with those settings, I haven’t changed anything related to the map in ages as I’ve been working on the mechanics so I was surprised to see it was gone when I moved the camera back over to that side of the map.
HOWEVER - I have noticed that if I unlock the transform and change the height of the river by moving it up the z axis, I can make it look as it used to
I’d love it if I could just keep the landscape as is and then move the river back up to where it was but alas there’s something stopping it and I’ve spent a whole day trying to fix it to no avail (even going into the Water HLOD material and changing the fixed z height on and off to see if that works but no luck.
I’ve also changed the overall landscape height back to 0 - it was down by about 40 or so which I realise is not good practice, this was my first project - but again it didn’t affect the river at all, it’s just stuck where it is.
Has anyone else experienced something similar? Sorry if I’m missing something super obvious here it’s just really bothering me as I was so happy with everything and super excited to ship it out to friends for testing but this is such a glaring omission from it that I’d love to sort it.
Thanks in advance for anyone with any advice - much appreciated if so.
To fix the river height issue in Unreal Engine, try these steps:
Use Fixed Water Depth: In your waterbody material, enable UseFixedWaterDepth and set the Fixed Water Depth value.
Enable Edit Layers: Make sure your landscape has edit layers enabled to allow the river to conform to the terrain.
Adjust River Actor: Merge multiple river actors into one spline and set the blend mode to ‘Min’ for a smoother transition.
Check Landscape Resolution: Ensure your landscape resolution is high enough to prevent disruptions.
Thank you so much for your help - your first piece of advice worked wonders on it’s own.
What I did was disable edit layers and then I was able to raise the river actor to where it originally was - now I can toggle that setting on and off if I need to and it stays in the right place.
This was EXACTLY what I was looking for - thank you so much for your time, you are a wonderful person.
