Layers Overview

Understand layers, the Layers Panel, and how to add content to your scenes.

Every piece of content in your scene — cameras, displays, images, text, widgets — is a layer. Layers stack on top of each other, and you control their order, visibility, and position to build your layout.

Adding Layers

There are two ways to add content to a scene:

Toolbar (bottom of viewport)

The Toolbar has six tool buttons, each opening a different flyout:

ToolWhat It Adds
TextCustom text overlays
MediaImages, videos, GIFs, slideshows, audio files
BrowserWeb pages, overlays, and interactive content
EffectsRegion-based canvas effects (blur, pixelate, etc.)
WidgetsInteractive stream widgets (chat, goals, counters)
AlertsAlert overlays for stream events

Sources Panel (left side)

The Sources Panel lists available hardware sources — cameras, capture cards, displays, windows, and audio devices. Click any source to add it to your scene.

Available Layer Types

Layer TypeDescription
Video DeviceWebcam, capture card, or virtual camera
Display CaptureApplication window or entire desktop

ImageStatic images (png, jpg, jpeg, gif, webp)

TextCustomizable text with fonts, colors, and styling
Effect RegionBlur, pixelate, and other canvas-level effects

The Layers Panel

The Layers Panel sits below the Sources Panel on the left side. It shows every layer in the active scene, ordered by z-index — layers at the top render in front.

Reordering

Drag a layer up or down in the list to change its stacking order.

Hiding

Click the eye icon next to a layer to toggle visibility. The layer stays in the scene but won't render on canvas.

Locking

Click the lock icon to prevent accidental moves or resizes. Locked layers can still be selected from the Layers Panel.

Renaming

Right-click a layer and select Rename, then type the new name.

Deleting

Select a layer and press Delete, or right-click and choose Delete.

Context Menu

Right-click any layer for quick access to:

  • Show / Hide — Toggle visibility
  • Lock / Unlock — Toggle movement lock
  • Rename — Edit the layer name
  • Properties — Open the Inspector Panel
  • Make Global — Persist this source across all scenes
  • Always on Top — Render above effect regions
  • Delete — Remove the layer

Global Sources

Mark a source as Global (via right-click → Make Global) to keep it across every scene in your collection. Your webcam and alert overlay are great candidates. Deleting a global source removes it from all scenes at once.

Always on Top

Sources marked Always on Top render above all effect regions (blur, pixelate, etc.). This is perfect for keeping your camera visible when applying blur effects to gameplay.
