I have in Modo f.e. four chairs. One real and three instances. Instaces are fake objects which have only position, rotation and scale values in space without any mesh. I may export fbx of one real mesh and for example position, rotation and scale values of every instance object (array of values exported by python script). Then I would like to import that one mesh to scene and import in some way position, rotation and scale values of that multiple instances of one object to set it automatically not manually. Is that possible?
Best way would be make some script which allow point object which has to be replicated and give possibility of paste data values inside Unreal 4 f.e. [name01, positionX,positionY,positionZ, rotationX,rotationY,rotationZ, scaleX,scaleY,scaleZ], [name02, positionX,positionY,positionZ, rotationX,rotationY,rotationZ, scaleX,scaleY,scaleZ] etc… . This should replicate object multiply times and set all values from that pasted data. This should set whole scene in seconds from modelling software to Unreal Engine 4 scene editor.
In my opion its better for some people to build scene inside 3d modelling app becouse its easy to correct mesh, UV, setting up whole scene meshes in software enviroment you like much and which is dedicated for that (ergonomic building scene with instances and replicators). I think this should be helpfull for many people. Please correct me if I`m wrong.
This has been requested and is something that is under consideration for use in UE4, but has not been implemented. The closest I’ve seen to this is a user on the forums made a plugin or app that could work with 3Ds Max to do this. I’m not sure the status of that project or the bugs associated with it possibly.
Thanks!

I hope in future you will develop some way to do that which will fit for every modelling software. I`m glad that is under consideration 
It would be very important in my workflow. The lack of this feature actually wastes lot of my time.
