This page provides information on the Corona Toolbar.
## **Overview**
---
The Chaos Corona Toolbar (also known as "Corona Official Toolbar" or "Corona Toolbar" in older versions) is a convenient tool for quickly accessing most Corona-specific objects and options. After installing Corona and launching 3ds Max, it will automatically open at startup.
## **Buttons**

Buttons from left to right:
