Creating Objects

All primitives live in the Primitives panel on the left.

Drag to place

Drag any shape thumbnail from the panel into the viewport to start creation. Release to drop.

Multi-phase creation (volume shapes)

1. Phase 1 — drag to define the base footprint (width & depth).
2. Phase 2 — move the mouse up/down to set height. Click to confirm.
3. Press Escape at any point to cancel.

Available primitives

Selecting Objects

Select by Name dialog

• Use the sidebar filter pills to show only Models, Containers, Lights, etc.
• Type in the search bar to filter by name in real time.
• Click any item to toggle its selection; highlighted items (green) are pending.
• Double-click an item to select it immediately and close the dialog.
• Select All selects everything currently visible (respects active filters and search).
• Select None clears the pending selection.
• Models and Lights can be selected together in the same confirmation.
• Click ▶ next to a Container to expand and see its child objects.

Transforming Objects

Select an object then use the gizmo in the viewport or type values directly in the Properties panel on the right.

Gizmo modes

Properties panel (right side)

• Click any transform field and type an exact numeric value, then press Enter.
• Position, Rotation, and Scale are shown in local space.
• Material section: change color, roughness, metalness, and opacity.
• Primitive section: live-adjust dimensions and polygon counts with sliders.

Multi-object transforms

When multiple objects are selected, the gizmo transforms all of them together relative to the last-selected object's pivot.

Lights

Add lights from the Lights panel on the left or via the Add Light menu.

Working with lights

• Click the light icon in the viewport to select it; the translate gizmo appears.
• Directional and Spot lights show a direction indicator line — drag the gizmo to repoint it.
• In the Properties panel: set color (color picker), intensity, range (Point/Spot), and cone angle (Spot).
• Toggle Enabled to turn a light on or off without deleting it.
• Toggle Shadow to enable shadow casting (requires WebGPU renderer).
• Multi-select lights with Ctrl+click or Select by Name to move several at once.

Containers (Groups)

Containers let you group models together so they can be transformed as a single unit.

Creating a container

1. Go to Scene > Add Container (or right-click in the scene list).
2. Select the container, then click Pick Object to Add… in the Properties panel.
3. Click any model in the viewport or use the pick-by-name dialog to add it.

Working with containers

• Selecting a container selects all its children for collective transforms.
• Individual child objects can still be selected and transformed independently.
• In Select by Name (H), click ▶ next to a container to expand its children.
• Remove objects from a container by selecting the child and clicking Remove from Container.
• Deleting a container removes the grouping but does not delete the child objects.

Particle Emitters

Emitters add dynamic particle effects to your scene. Add them from the Emitters panel on the left.

Controlling emitters

• Select an emitter in the Emitters panel or click its icon in the viewport.
• Use the translate gizmo (W) to reposition the emitter origin.
• Properties panel: adjust emission rate, particle size, speed, and lifetime.
• Toggle Enabled to pause or resume emission without deleting.

File Operations

Scene JSON format

Scene files are plain JSON — fully human-readable and easy to version-control. They store all meshes, lights, cameras, containers, emitters, and their transforms.
