Private addons?

How would i be able to “test” my addon in gmod 13 without uploading it to steam workshop…I know this question sounds stupid,but i need to know if it works.

Put it in the addons folder.

Oh wow,…I thought gmod 13 had a completely different addon system than 12…

it does, but it includes a legacy system,

I’ve added a Gmod12 addon to the Gmod13 addon folder and it isn’t showing up ingame… Am I missing something here?

It will not. The addon list shows only the workshop addons.

It won’t show up in the list, but it WILL work. Make sure the folder the addon’s in has everything it needs to work, then load up a game. I transferred over some Dead Space 2 player models from 12.
