Root part
From Kerbal Space Program Wiki
A root part is the first part placed in the VAB or SPH.
Properties
- The root part cannot be changed without detaching each and every dependent (connected) part from it. This typically requires starting construction from scratch.
- In VAB or SPH selecting the root part via left click selects the entire vessel, allowing it to be moved and rotated freely.
- Not every part can be used as a root part.
- The root part is the first part listed in any .craft file.
- This is the top of the dependency tree.
- When a craft separates into multiple vessels, the craft containing the original root part will become the active vessel.
- The part highest in the dependency tree in each vessel becomes that vessel's root part.
Trivia
- The most common root parts are command modules.
- The camera actually focuses on the center of mass of a vessel while in flight, not its root part.
- A mod, Select Root, allows you to change the root part of a vessel.
