Toolbar

The toolbar is located above the 3D viewport and includes network health, scene stats, selection mode switch, adding lights, adding cameras, and adding basic geometry objects.

Network Health

Click on the signal icon on the left side of the toolbar to expand the network health window.
The window displays the overall network quality status, response time, network stability, and packet loss rate.

Scene Stats

The scene stats icon is located to the right of the network health icon on the top toolbar. The color of the icon changes based on memory and video memory usage. For simplicity, the scene stats shows the maximum value of memory and video memory usage.
Hovering over the scene stats icon displays a simplified scene data bar, including low/medium/high resource usage status, total triangle count, and total object count in the scene.
Clicking on the scene stats icon expands the detailed information card. The scene stats card shows memory usage percentage, total triangles/vertices/objects count, current FPS, and the number of samples per pixel rendered.
The card also includes a pin icon for pinning the statistics to a small panel in the upper left corner of the 3D viewport.
When the current memory usage exceeds 90%, the scene stats card will automatically expand to alert you of high resource usage. The card will also provide suggestions for reducing resource usage. Additionally, a warning will appear in the render output window.

Adding Lights

Hover over the light icon on the toolbar to display the light source menu. Click on an light source menu item to add lights, including "Point Light," "Directional Light," "Area Light," and "Spotlight".

Adding Cameras

Click the camera icon on the toolbar to directly add a camera at the current view.

Adding Basic Geometry

Hover over the cube symbol icon on the toolbar to display the geometry menu. Click on a geometry menu item to add basic geometry objects including "Cube", "Plane", "Sphere", "Cylinder", "Cone", and "Torus".
