Here's the OceanicMapPack that you hopefully will be adding to the Test Server.
This will only require the players to join the server.
No external downloading AT ALL required

Instructions:

1. Open the Test Server's Dedicated Server folder.
2. Go to ModulesNativeSceneObj
3. Copy the files from the Scene Files folder in "OceanicMapPack" to that folder.
4. Copy the scenes.txt file from "OceanicMapPack" into the Native folder. You may wish to backup the old scenes.txt file first.
5. Go back out to the main Test Server's Dedicated Server folder. Edit the config you're using.
6. Add this:
