In Astroneer (early access on Steam, Windows 7), I'm having real difficulty finding enough copper/aluminum ores to build a vehicle. I'm in a mostly flat tropical world and all the mountains are a LONG way away. I have researched more than 20 of the alien blobs and I have the "TRUCK" tech unlocked but I can't build a "vehicle bay" yet because I cannot find the metals or their ores.
I consider vehicle acquisition a high priority because it would extend my range and carrying capacity a great deal and make gameplay a bit less grindsome.
