Jagged edges of textures in paint mode

Hi everyone,

I’m currently working on a arctic-themed level in UE 5.3 and running into a frustrating issue with landscape layer painting.

When painting paths (or transitions between layers) on my landscape, the edges are very jagged and strictly follow the underlying vertex grid.

  • Landscape Component Resolution: 128x128 verts

  • Overall Resolution: 1906x1906

  • Component Count: 225 (1x1 subsections)

I tried going into the Landscape Manage mode to change the Section Size / Resolution using Resample (and tried Expand), but strangely, it had absolutely zero visual effect on the landscape grid or the jagged edges - everything stayed exactly the same as before.

I managed to fix this in my previous UE4 learning project, but forgot how and to document it. I only remember that i didn’t touch the landscape data itself in the past. Just some settings.

I also tried to search on Google, without any solution.

Does anyone know how to fix this? I’m a beginner, please keep it simple, if possible. I’ll not be able to understand professional levels of UE topics.

Thanks!

Does your material have any LayerBlend nodes? If so, what is the blend type?
