Tree Window navigation
The Tree Window has multiple controls and navigation modes to help you move around efficiently.
Navigate using Standard, Trackball, or Traveler mode or use the universal zoom and focus controls that work in any mode. You can also navigate using alternative control schemes.
For camera controls and other keyboard shortcuts, see Hotkeys.
Navigation modes
There are three modes of navigation: Standard, Trackball, and Traveler. To switch between modes, right-click in the Tree Window and select Window > Navigation.
Standard mode (Default)
Standard mode lets you manipulate the scene like it’s surrounded by an imaginary trackball whose up vector is always aligned with the global z-axis. This navigation mode uses a pivot point to control where the camera’s looking and to define the point of rotation.
| Action | Three-button mouse | Two-button mouse | One-button mouse or touchpad |
|---|---|---|---|
| Pan | Middle-click and drag in any direction. | Hold Alt (macOS: hold Option) and click and drag in any direction. | |
| Rotate | Click and drag left and right or up and down. | ||
| Zoom | Rotate the mouse wheel or hold the left and middle buttons and drag up or down. To zoom and push the pivot point: Hold Shift and the left and middle buttons and drag up or down. | Hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down. | Swipe up or down or hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down. |
Trackball mode
Trackball mode lets you manipulate the scene as though it were surrounded by an imaginary trackball, without an up vector restriction. This navigation mode uses a pivot point to control where the camera’s looking and to define the point of rotation.
| Action | Three-button mouse | Two-button mouse | One-button mouse or touchpad |
|---|---|---|---|
| Pan | Middle-click and drag in any direction. | Hold Alt (macOS: hold Option) and click and drag in any direction. | |
| Rotate | Click and drag left and right or up and down. | ||
| Zoom | Rotate the mouse wheel or hold the left and middle buttons and drag up or down. To zoom and push the pivot point: Hold Shift and the left and middle buttons and drag up or down. | Hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down. | Swipe up or down or hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down. |
Traveler mode
Traveler mode lets you navigate a scene as though you’re a participant in it. Unlike the other modes, there is no pivot point. Instead, mouse motions are mapped to actions that move an imaginary traveler through the scene.
| Action | Three-button mouse | Two-button mouse | One-button mouse or touchpad |
|---|---|---|---|
| Walk | To keep a static viewpoint along the xy-axis, click and drag. Drag slower or faster to adjust the walking speed. To move to where the traveler is looking, hold Shift and click and drag. |
||
| Strafe (step sideways without changing the direction the viewer is looking) | Middle-click and drag left or right. | Hold Alt (macOS: hold Option) and click and drag left or right. | |
| Change the height of the traveler | Middle-click and drag up or down. | Hold Alt (macOS: hold Option) and click and drag up or down. | |
| Look up and down | Hold the left and middle buttons and drag up or down. | Hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down. | |
