If you check out the Community Content And Tools section there’s some tools for 3ds Max that can help you position your objects in 3ds Max and then transfer that information to UE4 so that you can more easily create your levels without having to place everything in UE4.
For me I’ve got some airplanes and it’s not as easy to place things in UE4 like the chairs, it’s much easier to position them in 3ds Max, so I’ve got a script that as long as the chair is already in the content browser in UE4 then I can run the script in 3ds Max and it’ll copy the positions and then I can just paste to UE4 and it will grab the object from the content browser and place it correctly. There’s also a tool someone else made that I haven’t checked out yet but might make it even easier.
