3D Viewport¶

The 3D Viewport is the central window where you see and edit the scene. It renders the currently loaded scene in real time, lets you navigate with a free-fly camera, and is where objects are selected and transformed.

Navigation¶

The camera is a free-fly / orbit camera. Movement only applies to the viewport your mouse started the drag in, so multiple viewports never move in lockstep.

Action	Control
Look around (fly)	Hold right mouse and move
Move while flying	Hold a mouse button and use `W` `A` `S` `D`, with `E` / `Q` for up / down
Orbit	`Alt` + left mouse drag
Pan	Middle mouse drag
Zoom	Mouse wheel (or two-finger scroll)
Faster movement	Hold `Shift` while moving
Adjust fly speed	Hold right mouse and scroll (when enabled in Preferences)
Focus selection	Frame the selected object(s) with the focus key

The movement and gizmo keys depend on the active keymap preset (Blender by default) and can be remapped in Preferences. The current fly speed multiplier is shown on the right of the toolbar.

Orientation cube¶

The cube in the top-right corner shows the current view orientation. Click an axis to snap the camera to that side, or drag the cube to rotate the view. Each viewport has its own cube; it is hidden while a viewport is locked to a scene camera.

Selecting objects¶

Click an object to select it.
Click-drag on empty space to box-select multiple objects.
Hold Ctrl while clicking or box-selecting to add to the current selection.

Selection is shared across all viewports and with the Graph window. Only objects flagged as selectable can be picked.

Transform gizmo¶

When an object is selected, a transform gizmo is drawn on it. The mode is chosen from the toolbar (or with the gizmo keys):

Tool	Description
Translate	Move the object along an axis or plane.
Rotate	Rotate around an axis.
Scale	Scale along an axis or uniformly.
World / Local	Toggle whether the gizmo aligns to world or to the object’s local axes.

Holding Ctrl while dragging snaps to fixed increments. Holding Shift transforms only the object itself without carrying its children along. Each viewport keeps its own gizmo state.

Toolbar¶

The toolbar across the top of the viewport holds, from left to right:

Control	Description
Translate / Rotate / Scale	The active transform gizmo mode.
World / Local	Gizmo space toggle.
Grid	Show or hide the ground grid.
Collision Mesh	Show or hide collision-mesh wireframes.
Collision Bodies	Show or hide collider shapes.
Icons	Show or hide the object billboards (camera, light, audio and generic object icons).
Camera	Mirror the view onto a scene camera (see below).
Resolution	Switch between free and camera resolution (see below).
Cam Speed	The current fly-speed multiplier.

These overlay toggles are local to each viewport, so different viewports can show different helpers at the same time.

Placing prefabs¶

Drag a prefab asset from the Files window into the viewport to spawn an instance. It is placed in front of the camera and selected so you can position it right away.

Camera preview¶

A viewport can mirror a Camera from the scene to preview exactly what that camera frames.

Pick a camera from the Camera dropdown in the toolbar (or “Free Camera” to fly freely).
While locked, the view continuously matches the camera object’s position, rotation, FOV and aspect ratio. Free-fly controls and the orientation cube are disabled.
The bound camera’s own icon and frustum are hidden in that viewport so they don’t block the view.

Resolution mode¶

The Resolution toggle (enabled once a camera is bound) chooses how the preview is rendered:

Mode	Description
Free	Renders at the viewport’s own pixel density, letterboxed to the camera’s aspect ratio.
Camera	Renders at the camera’s native resolution (for example 320x240) for an authentic, low-res preview.

In Camera resolution mode the viewport becomes a clean preview: the grid, collision overlays and icons are all forced off (and their toolbar toggles greyed out) so you see only the rendered image, just like the game would output it.

Multiple viewports¶

You can open any number of viewports, each with its own camera, overlay toggles and camera binding.

Open a new one with View > New Viewport, or by right-clicking a viewport tab and choosing New Viewport.
Close a viewport with the x on its tab, like any other window.
Open viewports are remembered between sessions; the default layout always has one.
View > Reset Layout collapses back to a single default viewport.

A typical use is to keep one free-fly viewport for editing and a second one locked to a gameplay camera in camera-resolution mode to preview the final framing.
