## **Key Features**
---
1. When managing a scene with numerous lights, cameras, or proxies, you can hide columns that are not currently in use to declutter the display. Any hidden columns can be revealed from the context menu by selection of **Unhide all** option. Additionally, you can select which columns are visible by using the **Column Visibility** button.
2. Columns that are hidden in the lister remain hidden even after closing and reopening 3ds Max.
3. You have the ability to increase/decrease the scrolling speed in the Corona lister parameter spinbox with Ctrl/Alt. Specifically, holding Ctrl and dragging your mouse to make the spinbox parameter value change quickly. If you hold Alt and drag, the value changes slowly.
4. The **Toggle All** row offers options that control the whole list.
5. Selection toggle buttons are available for individual listed objects and also for the whole list to provide quick and easy selection as per user need.
6. You can also choose to make any instance unique by right-clicking and selecting the "**Make unique**" option for Cameras, Lights, and Proxies.
7. From Corona 12 onwards, you can reorder Corona Lister tabs by dragging them with the mouse, providing a customizable user experience.
## **The Interface Tabs**
---
Corona Lister consists of four main tabs: **Cameras**, ** Displacement**, **Lights**, and **Proxies**.
## **Streamlined Control with "Toggle All"**
---
The **Toggle All** row offers buttons and checkboxes that make quick changes to all items visible in each list. Buttons and checkboxes vary depending on the active tab in the Corona Lister. For example, in the **Lights **tab, there is an additional **On **checkbox to enable or disable all Corona lights, and in the **Proxies **tab, there is an additional dropdown “Previz type” button to change the display for all proxies visible in the Corona lister. Similarly, you can use the button in the **Actions **column to apply changes to all visible items in the Corona lister.
## **Selected and Actions Columns**

The **Selected** column allows you to quickly select each item listed. The **Actions** column provides quick access to make changes to the items, with the options varying depending on the active tab.

## **Example Scene**
---
In this example, we are using a simple interior scene with several Corona lights. The ceiling lights have been instanced and grouped together in the Corona Lister. To change and affect all the values of instanced lights, simply change the parameter of a single light. The side rectangle lights and floor lamp lights are listed separately in the Corona Lister because they are unique and must be adjusted individually to achieve the desired lighting effect. Also, there are multiple Corona Cameras in the scene which are listed in the Corona Lister. All settings can be quickly changed and managed using the Corona Lister.
