Map Generator- Please Critique!

Thanks and good luck!

So after a buttload of research I am trying to instance my tiles based on some Tile Class Blueprints.

Currently I create an instanced mesh using a poorly defined actor variable. I need to spawn Tile Classes, and then be able to modify them during and after map generation.

Right now I am trying to figure out how I can change the class of a spawned Tile from Tile_Parent to Tile_Grassland for instance. Would that be the “Set Value as Class” node?
