In the mission I'm working on, the test starts me out in ESD, and I jump right to the first mission map. How do I set it up to transition to sector space (Assuming that the mission doesn't begin there), and fly to the planet I have in mind myself?
Check out these tutorials, they may offer some help. In essence, once you place the first objective on a map, you can then add a map-transition element to the Story tab. In this map-transition element you select where the player should go to enter the new map, so you could choose any mission-doors from Sector Space as the entry point and the player will have to leave ESD first before they can enter your actual mission-map.
