In my OldAbandonedSettlement mod I exclude all surfaces except Nauvis, will this mod override this? Also would it be possible to exclude/include seperate ruin packs per planet e.g only spawn OldAbandonedSettlements on nauvis but allow base ruins to spawn on other planets?
Surface exclude/include always applies to all ruins. When you stack multiple sets together, Ruins mod has no idea which mod a ruin comes from, so to implement this it would probably be best to add optional section with planet settings to ruin format.
So it would require ruin sets that insert into a table for each planet rather than one big table, e.g List of planets and for each planet a ruin set entry so if the planet-name_ruin_set table has a ruin set then it gets spawned else that surface is ignored, it would be a nice feature and ruin sets could be designed for a particular planet. This can only be done in the main mod I guess.
