ive got an idea for building a planetside mine poi. I've looked at some of the ingame planet pois like 'abandoned mine' and 'deep mine (epic)', and the question I have is can you use the rock and resource terrains from asteriods and use them in planet pois. like build the walls and roof of the mine tunnels in the rock terrain? im assuming any mine build in these materials underground would still be wrapped in a later of filler blocks if so. thank you in advance Stellar Titan
You can have terrain parts in POIs. See, for example, the "Burial Chamber" mission in the campaign story i.e. the "spider dungeon".
