How to use multiple landscapes?

How to use multiple landscapes in unreal 5.1?? The mesh normals of the landscape borders seems to be calculated in some other directions which is causing shading and slope blending issues along the edges! Here is the image


Landscape 1 on right and landscape 2 on left

I still can’t figure this out!

Fixed it! I am using material only blueprint brush with custom displacement texture and setting the alpha value of the brush to zero fixes it! But, one question still remains and that is what’s the best way to sculpt two different landscapes because the current workflow is tedious!
