Does ObPlacer XML work with FSX? If you have FSUIPC installed it should, but the tool can not read the FSX style library object XML file. So it is not really adviced to use it for pure FSX development. And because there are other well-featured alternatives for FSX available already, I have decided not to make an update for ObPlacer XML anymore. I will spend that time on other tools. Looking for a freeware object placement tool for FSX that has a better user interface than the default OPT tool? Try WhisPlacer.
