Im new to this, I know how to install adv dupe models but how do i access them in gmod
Make sure you installed them to the correct path, go under the ‘Construction’ tab when in-game, and it should be the first on the list (Advanced Duplicator). If so, click on it and on the context menu there should be a list of all the installed Duplications. Click on the one you want and press ‘Open’, and wait for the ghosting to finish and click on the floor to paste it. If not, then you probably don’t have Advanced Duplicator installed correctly. If not any of that, then you aren’t installing the duplications to the correct place.
