Every time an image is Snapped a code is saved under the Camera tab in the control panel. If a valid code is entered into the box and UseCode is clicked. The camera will jump to the position represented by that code.
Click Snap in the control panel or press space to render with the current configuration. Note that this may take time depending on the settings.
In the Lighting tab of the control panel, enter a light ID (0 - 3) and click get. The properties of the light should appear. After making adjustments, click update to update the light.
To load a scene, click LoadSceneA or LoadSceneB under the Scenes tab in the control panel. Note that while the WebGL preview will update automatically, the ray traced image will not update until another image is Snapped.
