To open/close the Editor, type "/TSE" or "/ToggleSystemEditor" in the chat.

"Insert" / "Delete" to move up and down the hierarchy list on the left.

"Page Up" / "Page Down" to move up and down the parameters list on the right.

"[" / "]" to increase or decrease the currently selected parameter when applicable. Also used to Confirm or Cancel any confirmation popups.

"Home" to activate the currently selected button or submenu when applicable.

"End" to back out of the current submenu.

"Enter" to open chat log to directly enter a value for a parameter when applicable.

On the left, you will see a list of all celestial bodies currently in the world and how they are arranged. The very top element marked "Add New System" contains the controls for adding a new system root body. Selecting an element on the left will show all of its values in the parameter panel on the right.

Each element will have:
-The name of the body
-Icon on the left indicating whether it is a star, gas giant, or planet
-Indentation indicating how far down the hierarchy the body is (i.e. the star may have no indentation, the planet orbiting it may be indented once, and the moon orbiting the planet may be indented twice)
-(Optional) A circular arrow icon between two elements marking them as siblings

On the right, you will see a list of parameters for the currently selected body. The parameters displayed will depend on which body and submenu are currently selected.

<Planet Type> (Only for "Add New Planet")
The planet type to be spawned. Listed as the SubtypeIds of planet definitions.

<Radius>
Radius of the planet to be spawned in km.

<Root Position> (Only when new system)
Root position of new system centered around new planet.

<Orbit Radius> (Only when not new system)
Orbit radius of new planet.

<Name>
Name of body as it will appear on automatic GPS markers. Can be randomly generated or set directly via chat input.

<Planet Type> (Only for type "Planet")
The planet type (SubtypeId). Changing this value will cause voxel planet to be deleted and replaced after a few seconds.

<Radius> (Only for type "Planet")
Radius of planet in km. Changing this value will cause voxel planet to be deleted and replaced after a few seconds.

<Orbit Zone Radius>
Radius around body that defines its "Orbit Zone". Multiplier represents the number of planet radii above the planet surface that the zone extends. For instance, a 120 km radius with an Orbit Zone Radius of 5.0x will extend 600 km above the surface (or 720 km from the center).

Entering a body's Orbit Zone will teleport all entities to the real voxel planet (and away from proxy space). All grids/players within this zone will move along with the planet along its orbit.

<Surface Zone Radius> (Only for type "Planet")
Radius around body that defines its "Surface Zone". Multiplier represents the number of planet radii above the planet surface that the zone extends. For instance, a 120 km radius with an Surface Zone Radius of 1.0x will extend 120 km above the surface (or 240 km from the center).

Entering a planet's Surface Zone will teleport all entities to the appropriate position based on the planet's current rotation. All grids/players within this zone will move along with the planet's surface while the sky and other bodies appear to rotate above. Only terrestrial planets have a Surface Zone.

<Proxy Fadeout Height> (Only for type "Planet")
Multiplier controlling the relative height at which the planet proxy will begin to fade/shrink and reveal the voxel planet. By default, the proxy will only fade out fairly close to the planet, but this can be increased to reveal the voxels sooner. A value of 1.0 will start fading out the proxy immediately after entering the Surface Zone. This is a completely cosmetic setting and does not affect any gameplay.

<Proxy Scale>
Multiplier for the size that a body and its entire zone appear within proxy space. Setting this value above 1.0 can make planets appear larger that they really are in proxy space. For instance, a planet with radius 120 km and a Proxy Scale of 5.0 will appear to be have a radius of 600 km in proxy space. When entering or exiting the Orbit Zone for this body, all distances and velocities will be transformed appropriately to make things visually seamless.

This can allow for making planets that appear as large as their real-life counterparts in proxy space, but have more reasonably-sized voxel counterparts when you approach. It also allows for creating "mini" solar systems with planets that are very close together and much smaller than normal while in proxy space (making interplanetary travel easy), but are normal sized when you land on them.

<Rotation Period> (Only for type "Planet")
Number of seconds that it takes for the planet to rotate once. Positive values rotate counterclockwise. Negative values are clockwise.

<Root Position> (Only for "Root" bodies with no parent)
Position in world space of this root body.

<Sibling Weight> (Only for bodies with siblings)
Controls the relative mass of sibling bodies with respect to how their orbits are shaped. Values of 0 or 1 will have one body completely orbit the other. A value of 0.5 will have them orbit each other perfectly balanced (as all things should be).

<Edit Orbit Info> (Only for non-"Root" bodies that have a parent)
Opens the Orbit Info submenu.

<Edit Star Info> (Only for type "Star")
Opens the Star Info submenu.

<Set/Add Sibling> (Only for bodies without siblings)
Opens Sibling submenu. Can select options to either create a new body or assign an existing body to be the sibling of the selected body.

<Swap With Sibling> (Only for bodies with siblings)
Swaps the current body with its sibling in the hierarchy.

<Detach From Sibling> (Only for bodies with siblings)
Detaches the current body from its sibling.

<Set Parent>
Sets body to be either a child of another selected body or a new root body.

<Add Child>
Opens Add New Planet / Gas Giant / Star submenu. The new body will be made a child of the selected body.

<Delete Real Planet> (Only for type "Planet")
Deletes and recreates the voxel planet associated with the current planet body.

<DELETE>
Completely removes the current body.

<DELETE HIERARCHY>
Completely removes the current body and all of its siblings and children.

<Semimajor Axis>
Orbital radius (can stretch if Eccentricity is > 0).

<Eccentricity>
How elliptical the orbit is. 0 is perfectly circular.

<Pitch>
Pitch angle of orbital plane.

<Roll>
Roll angle of orbital plane.

<Yaw>
Yaw angle of orbital plane.
