FIRST YOU NEED TO BUY MY 10$ PERMA PRO- Actually no. Believe it or not, this is built into Gmod. You should stop buying perma prop addons So what is persistence? A bit self explanatory. It makes props "persist" even between map changes. You may have noticed this option when holding C and right clicking on a prop: Yeah. This is exactly what im talking about. So first, spawn the amount of props you so desire, position and angle them like you want. Afterwards, hold C and right click on the props you've spawned, and pick "Make Persistent". Once you are done making all the props you want persistent, reload the map by typing changelevel <mapname> into the server console. (Doing "exit" or "quit" or "restarting" through server control panels does NOT work (It may or may not. Although, all the control panels ive seen has failed so far)!) Once done, the server will reload the map (or change, if you oddly enough typed in a different map). And as expected, the props are still there! The persistence save file will be located in garrysmod\data\persist\<mapname>_.txt WARNING: It is suggested you make a backup of this file once you have finished making all the props you want permanent, because if the map gets cleaned, or the props somehow get removed, you will have to start over. Many people have been led to believe that persistence served no purpose, and many doesnt even believe it works. You dont need a perma prop addon from scriptfodder, or wherever you get your addons from. It is waste of money.
