Point Click Placement Tool will allow to you paint objects to the scene very similar to how the terrain tools allows you to paint trees to the terrain. The difference is not only can you use this tool to paint objects to terrains but you can also paint objects to other types of objects. For example you want to paint fences on a cube or want to add waypoints to a plane.
Help boxes have been added so that it is easy to see what a control does by just checking a box to show help. You can create groups for your objects to be added to or select an existing object in the scene to use. There is also a preview window that can be enabled or disabled to show the current object you have chosen.
