Why when I import mesh, the 0 0 0 of coordinates (x, y, z) become a pivot point and UE4 ignore real pivot point of mesh? This problem appears only with meshes which are not placed on 0 0 0 of coordinates - I have very much so meshes (a few hundreds), so, it’s not possible to change placing of each m…

Unreal always uses 0,0,0 as the pivot point of a mesh on import. But you could uncheck “Transform Vertex to Absolute” so your current Pivot Point should be zeroed out.
