hey I hope it's okay if I ask here, I absolutely love this scene and I've figured out where to put scenes in AA2 files but I can't seem to find out how it works and how to activate them if you could help me out please

basically how it works is when you are in either the editor or on the game you press F12 and after that 2 windows will pop up, one is to control everything related to the character and props, the other one is a smaller one to load scenes and poses
