Mapping for ETJump
Here you will find simple guide on how to start mapping for ETJump mod.
To start mapping it's recommended to make a clean ET install seperate from your regular ET install. This way you won't accidentally use custom assets provided by other maps in your map. A third, untouched install could also come in handy when creating a pk3. This install should only be used to test if you have included every custom asset in your pk3.
To create maps, you need GTK Radiant. You can get it here.
In order to play your own maps you create, you need ETJump server files. These are not included in pk3 that you download from a server, instead you need to download them from ETJump website.

ETJump assets include entities and shaders that are useful when creating maps for ETJump. You can get the assets from GitHub.
