The wall is not tileable.

Development Asset Creation

  1. In the image, when I copy the plane I created in Blender 3D and opened its UVs and place them side by side, they do not become tileable.
  2. In the image, I create a plane in Unreal, place two planes side by side, and they become tileable.
    My question is: why are the objects I create in Blender and export not tileable?
