H3-Sapien, part of the Halo 3 Editing Kit, is a visual scenario and BSP editor used to populate levels with objects, configure BSP cluster data like wind and sound environments, compile scripts, and more. Sapien shares some systems with Halo 3 itself, including its AI system to support interactive AI scripting and debugging.
It is roughly analogous to Forge found in later Halo titles, Users primarily interact with Sapien's windows and menus, but the Game Window also includes a scripting console which has support for debug commands, and by using Tab you can switch to player mode to interact with the simulation in real time.
The game window is the main interface when interacting with objects in the level. It is also where you can run commands by pressing the ~ (tilde) key.
Movement of the camera is done in the same way as the in-game debug camera; hold the middle mouse button plus:
- Use the mouse to aim
- Click the right mouse button to zoom in and out.
- Move with W, A, S, and D
- Go up with R and down with F
- Change camera speed by pressing Shift
- Switch to player mode with Tab and by using Backspace you can toggle between third person, freecam, and first person.
The Hierarchy view displays all the objects currently placed in the game and organizes them by type. The left pane of the window shows the Hierarchy tree and currently selected type, and the right pane shows the objects of this selected group or type that are currently placed in the level.
This window contains settings for the currently active tool mode, such as object placement, decorator painting, or cluster properties application. The currently active tool depends on the selected hierarchy view item.
The Properties palette window displays the properties for the currently selected hierarchy item. The type of object can be changed or chosen in this display as well as various other properties such as the position and rotation of the object, and spawn flags that set various attributes for the object.
You'll be able to highlight clusters by using your cursor in the game window and left clicking to set it as your active cluster.
Prints debug info for loaded tags along with actions taken by the user.
Some of these shortcuts are only used in certain windows or editor modes.

- Control+Click: Select a group of objects or keep previously placed objects selected. This will only select the object you specifically click in the hierarchy list. Useful for deleting multiple objects or moving them all at once.

At startup, Sapien will load
editor_init.txt if present in the same folder. This file can contain console commands, one per line, which are executed automatically for you. For example:
