UE 5.7 Water Plugin - Baking fails after adding an additional WaterRiver

Hello everyone,

I’m a game designer currently working with the Water plugin in Unreal Engine 5.7, and I’ve run into a frustrating baking issue. I’m hoping someone here might know a workaround or a fix.

Here is the current situation:

  • Previous State: I successfully set up and baked 2 WaterRiver components in the map. It was working perfectly. (Note: The last successful bake was over a month ago).

  • The Problem: Recently, I tried to add an additional river, but now the baking process completely fails.

  • Current Status: What’s worse is that even if I try to bake the current state as-is (or revert to the previous working state), the bake simply does not work anymore.

I haven’t changed any major project settings since the last successful bake, so I’m stuck trying to figure out what broke.

Has anyone encountered this issue where the Water plugin suddenly stops baking altogether? What could be the potential cause of this, and how can I fix it?

Any advice or suggestions would be greatly appreciated. Thank you!

Hello there @Anonymous_d61fbdbb28ddee46718a7ebe5b8748f3 !

That’s quite a particular isssue you are facing, as the build was baking with no problems before adding the third river, which suggest that everything should be fine with your setup and the plugin itself. It’s more likely that the additional water body is having a faulty interaction, somewhere in your scene.

Looking around the community, the closest scenario I could find was combining a river with shallow water, resulting in failure to render. Please check if their methods of resolution can work in your scene:

For further actions, we will need to know the specific error you are getting on the failed bake. Is there a log or crash report you can share here?
