For example, you have an empty house, and want to place furniture where YOU want it, or that blank trophy on the wall, not where its hidden until activated. I have no idea about anything to do with knowing what is near the crosshair, etc. PlaceAtMe would place it where you are standing, correct?

Put it inn as deactivated and then activate it from a script.

If you want moveable furniture it's best to drop an activator and then activate then needed.

For moveable user placeable furniture look at.

You need an placeholder object you drop from invetory and then activate so it turns into an static.

Thank you!
