In a year or so of crafting textures, I've never looted a Large Striped Cotton Fabric Texture BP (Calypso technician BP) or Carabok Leather Texture BP (Arkadia technician BP), so it seems it's possible to take care of this. I believe I've never looted Calypso technician component blueprints (Hardened Metal Plating and Galaxy SI Ion Conductors) either. Arkadian technician component blueprints however drop in large amounts, and that's indeed annoying.
