to anyone who had this queation. as far as i see there is no level. you jsut change the entities of the enviornment and the settings of the graph. and you technically have a different level. i ended up creating an array of entitis tha hold level settings. they are being loaded depends on a "level" number which is saved ina jason .

Thank you sir I have continued my questions in this post once realized v2 is an old one https://developer.apple.com/forums/thread/837774 But simply my question is what are the actual 123 steps to properly import to xcode. What exactly should i do with the content (been told to export as a .reality filefrom RCP3), and then how to get it into my xcode. Drag it in the xcode outliner? and then what command exactly to use to save it into an entity variable I guess i should "do{try let entity = ...}" but im not sure exactly what command to use

Sure, you are welcome to show it to the relevant guys in the department, can be an awesome addition to the RCP ^_^ https://feedbackassistant.apple.com/feedback/23684633 Thanks
