Hey,
I'm trying to test a new victory ship design for the <40h achievment but somehow I can't figure out how to unlock solar edge as a destination in sandbox.
I can travel to aqulio but solar edge keeps greyed out on the map even after importing my completed normal run savegame. Is it not possible in sandbox?

Thanks and regards,
Rob

Where is it greyded out ?

I can confirm it is possible to have the solar system edge as a destination for a platform in sandbox mod :

It is necessary to have "promethium science pack" researched, which can be achieved by typing /cheat all or by accepting the pop up at the start, proposing player to have all researched granted.

Bring up the research screen with T, then find the research that unlocks the solar system edge. It's the promethium science pack. Shift-click the "research" button to make it researched (only possible in map editor mode).

Thank you guys! That solved it. Silly me didn't think about researching promethium.
