Im making a TTT map and wanted to add a moving prop in the map. I am using source multitool and when I go to add a func_tracktrain there is no option. I can manually set the entity to func_tracktrain, however that removes itself once I click on it again. Anyone know why this is, how to fix it, suggestions or links to how to setup something like sdk for gmod mapping?
Additionally here is the screenshot on what options I have.
