My day work put me in a situation where I needed to download marketplace assets on a Linux machine. Given the fact that Linux does not support the Epic Launcher and that the Epic Launcher is the only way to download assets, this presented a problem.
I came up with a solution for me, maybe others would like it too.
I made a node.js app that runs in your shell/command prompt/powershell that gives you access to downloading marketplace assets you own. You need to have NodeJS installed, and to log in using the app, for it to work. It will download assets to your current working directory in a subfolder called ‘download’. It doesn’t have any advanced features like download resuming, caching, etc. like Epic’s launcher, but if you’re in a pinch, it works. At least it works on Windows / Ubuntu (thats all I’ve tested).
If you have nodejs installed, getting it is as simple as
npm install -g Allar/ue4-mp-downloader
Theres bound to be bugs. For example, currently Code Plugins result in a 403 (Forbidden) error, and it takes up a little bit more memory than it should. Looking for help with either.
