Hello!
The correct way to import it is, in Blender, to make all the pieces “clear” their locations, and you, from the Engine, rearrange everything. This is pretty simple, in Blender [Alt] + [G] / [R] / [S] (Location, Rotation, Scale) reset their values to zero.
So, select everything, clear all transformations from blender, and import to Unreal to rearrange from the engine.
Maybe it is a way to import a mesh and that it respects its point of origin regardless of its position in the 3D program scene, but the correct way, or at least what I’ve always seen, is to reset everything to 0,0,0 from the beginning.
Best lucks!
