This guide contains a list of possible issues with the Chaos Corona Toolbar and solutions to them.
Note: the toolbar is called "Corona Renderer Official Toolbar" in Corona 7 and older, and "Chaos Corona Toolbar" in Corona 8 and newer.
1. How to reset the Chaos Corona Toolbar to its initial state?
Removing the Chaos Corona Toolbar from the Customize User Interface > Toolbars dialog and restarting 3ds Max will result in resetting the toolbar to its initial state - without any previously added user icons, and with previously removed icons restored. This is recommended as the first step when dealing with any issues related to the toolbar (such as missing buttons, no reaction to mouse clicks, incorrect name, or other issues listed in this guide).
Here is how to do it:
- Go to Customize > Customize User Interface > Toolbars, then click on the drop-down list in the top-right part of the window, and look for the "Chaos Corona Toolbar":
- Remove this item by pressing the "Delete..." button:
Upon 3ds Max restart, the Chaos Corona Toolbar will be reset to its initial state.
If this doesn't help, you can manually unpack the installer and from unpacked directory copy "Autodesk\3ds Max 20XX\UI_ln" folder to the corresponding location in 3ds Max folder: (default is C:\Program Files\Autodesk\3ds Max 20XX).
If the issue is not resolved after 3ds Max restart, please contact us.
2. I can't find the toolbar, it's not visible!
This could mean that the toolbar is hidden. If that's the case, simply unhide it by right-clicking in the 3ds Max UI (for example on the top 3ds Max menu) and selecting the Chaos Corona Toolbar:
If the above solution does not work, please delete the Chaos Corona Toolbar as instructed in point 1 above, and restart 3ds Max. This will restore the toolbar to its initial state.
3. "Corona Toolbar" or other name is visible instead of "Chaos Corona Toolbar"
If you can see a toolbar called "Corona Toolbar" or similar, but not "Chaos Corona Toolbar", either floating separately or in addition to the official one, it is an old version and it can be safely removed. To remove it, follow the procedure explained in point 1. "How to reset the Chaos Corona Toolbar to its initial state?".
Note: "Corona Toolbar" is an old name that we used for the official toolbar in the first versions of Corona Renderer where it was included. Later, we found out that this name conflicts with some 3rd-party toolbars because 3ds Max identifies toolbars by names. Therefore, we decided to rename our toolbar to "Chaos Corona Official Toolbar" (in Corona Renderer 5 and older),"Corona Renderer Official Toolbar" (in Corona Renderer 6 and newer), and "Chaos Corona Toolbar" (following Corona Renderer version 8 and newer) so that it does not conflict with the other ones.
4. The toolbar is visible, but nothing happens when clicking the icons, and there are random characters in the tooltips when hovering the mouse cursor over any of the toolbar icons.
This issue happens rarely and we are not sure what exactly is causing it. If you encounter it, please contact us so that we can investigate it and provide a proper solution.
5. I have added my own button in the Chaos Corona Toolbar, but it disappeared!
In Corona Renderer 8 and newer: adding custom buttons to the toolbar is no longer supported. If you wish to have custom buttons in the 3ds Max UI, please create a separate toolbar.
In Corona Renderer 6, or 7: you can add your custom buttons to the Corona Renderer Official Toolbar.
In Corona Renderer 5 or older: If you wish to add your own buttons, you need to create your own toolbar or place them in a different part of the 3ds Max UI.
6. My problem is not described in this guide!
If you are having some other problem with the Chaos Corona Toolbar, which is not described here, please contact us about it and provide as many details as possible (a good description of the problem, screenshots showing the problem, the versions of Windows, 3ds Max, and Corona that you are using).
