Depence comes with two render modes, "Photo Realistic" and "CAD View". Within the Render Window Menu, you can change the current mode by using the "Display" menu item. Please note that only one "Photo Realistic" view can be activated at a time.
Each Render View has a Live-Mode button, which enables a non-editable mode in the currently active editor. This is perfect for show programming. If the live-mode is active, only fixtures can be selected.
