I created a landscape in UE 5, started sculpting out area for river, added a river, and thigns somehow got out of control. I can’t get the part of the landscape where the river is to go back to a pure flat state so that I can start over sculpting.
No matter what I do (Sculpt, Smooth, Flatten) these tall sharp spires form, preventing me from flattening things out.
Hey there @bhuether! Do you have edit layers enabled on the landscape? These spires could be drawn on another layer and would need to be flattened on that specific layer. If this is not the case, could you hide the meshes near the spires when sculpting and try to manipulate the spires again?
Is this option missing in your case by any chance? I noticed in one of the blogs I guess where the unreal version the blog used did not show the erase option being present?
Its not always present.
Likely its only there if you have editable layers.
So most cases you wouldnt have the option.
The way to remove the landscape is to re-image using an exported flat map.
If you want to limit this to just one landacape component, it wont be easy. But the best way would be to force the whole block into a really high configuration, export the generated heightmap, fix it in krita or any native 64bit program and re-import the heightfiled to fix things.
