Stuff only a certain race can make, is in their species file. If this is your race, you can edit the species file with the new items, if this is for another race you can make a patch for their species file. The code would look something like: Code: [ { "op" : "add", "path" : "/defaultBlueprints/tier1/-", "value" : { "item" : "yourfirstitem" } }, { "op" : "add", "path" : "/defaultBlueprints/tier1/-", "value" : { "item" : "yourseconditem" } }, { "op" : "add", "path" : "/defaultBlueprints/tier1/-", "value" : { "item" : "yourthirditem" } } ]
