So I'm trying to make a server for my friends and I to contribute to the BuildTheEarth project and this project requires the Terra 1 to 1 mod which I have installed on the server and I have no issues with that. The problem I'm facing is that in singleplayer, I can select the CubicEarth worldtype (which I am able to do in the aternos server too) and then I have to click on 'Customise' to change some options to suit the BTE project. Thing is, I don't know how to access it in Aternos.
If this helps, these are the options I need to change. I think access to server.properties is required:
Projection type: Build The Earth
Orientation: Upright
Smooth blending: On
Spawn roads: On
Advanced water: On
Elevation based ores: On
OSM Building Outlines On
Just to summarise, I'm able to generate a world with the CubicEarth world type in Aternos but I cannot figure out how to change the subproperties in the 'Customize' option which you can find in singeplayer.
