How to create new bases and launchpads

@SamTheFox Thanks a lot for all your explanations! Really helpful!

you cannot upload the craft in planetstudio, you upload the craft in the craft editor by opening the menu and pressing the upload icon

the same can be done with systems and planets

make sure that if you want people to explore your planet, you have to upload the planet in a system, and make sure that the planet has a launch site

@SamTheFox
Thanks for the patience with me….but here I got lost: do I have to use planet studio for that? And , if so, how do I upload that craft in planet studio?

increase the altitude of the structure onto the ocean surface, and add a launch location (upside-down teardrop with a circle in it)

@SamTheFox, thanks a lot!
For ground based it works fine!
I have a final question: how may I load one of floating bases available in the download crafts section and use as sea-based pads?

well you need to access the planet you want the base on FIRST, and open the structure menu and add whatever you want (and if you want to see the launchpad in map view you can turn on "show in map view" in the structure settings)

then save the planet and put it in a system

@SamTheFox yes either in planet studio or by placing bases in sites where I landed without planet studio

are you talking about in planetstudio?
