Floor ID

Walkable Mesh Tagger
BP_SDotUI3_WalkableTarget / Mouse Move
Meshes that are at the same height as the player is standing on are automatically considered a walkable mesh. Other meshes, like stairs need to be marked. This actor does just that.
Walkable Meshes
Place the blueprint near a meshes that the player should be able to walk on and add it to the array.
Note that this doesn't replace collision. Every Mesh in the scene that is within the players range needs to have a collision.
Cost Group
BP_SDotUI3_CostGroupThis blueprint can add a list of cost items to a sub level. This is to track additional costs by adding a streaming level.
