Looking to try and get some help with this. I was watching BlackJesus' video on making non-ELS cars, and in it he selects a box mesh being used as a collision for glass in polygon mode, opens the properties tab at the top, and then under ExternalState there is another drop down for DefaultCompatibility with a list of flags. I am unable to locate said tool on my Zmodeler (maybe due to the version?) and I wasn't sure if this is still necessary to do. If it's still necessary, because I know it has something to collision reactions, how do I enable it?
