Do you have a build team? And want to show your customer the build without them being able to destroy it or any other builds in the world? Then unwanted is the plugin for you!
UnWanted will make anyone who is not a Builder a spectator. A spectator can not build, destroy or interact with the environment in any way. But if the player is a Builder they will be able to do everything they normally would be able to do.
