So, the first example shows a solution if you have all the meshes already in your blueprint (BP_PlaceActor). Here these are SignalC and LampA. With the ForEachLoops you compare all entries of RowNames and MeshNames to find the equal pair. If they are equal, you want to get the location and rotation from the DataTable and set it for the mesh:
In the second example you first get all the actors which are a static mesh, store it in an array an then compare the two arrays like this:
For the second method you will have to place the static mesh already in your level. For the first method you just place the blueprint actor inside your level because all the meshes are in the blueprint.
