There is no posts cause there is no exo as of now. When they do spawn and are spotted, there will be new threads like these. [Smaren] --[T4 - Inhospitable Lush Color-Cycling Exoworld]-- [Inactive]
They will be pretty much the same as regular planets, with the additional exo-only materials like kindling mass, goo, petroleum, resin, and for T7 exos, lucent gems. Might also have rare exo only colored blocks as well. Resources however do not regenerate.
Personally I won’t bother with resources on exos due to multiple reasons tho. Much better to just ignore them mostly than get stressed over rushing there to get stuff before they’re all gone imo.
