The Avastar Preferences is actually a shortcut to the Avastar Add-on Preferences where you can setup some Add-on parameters. Normally you do not want to change anything here. However especially if you are a long time user or someone who knows much about Blender, then you possibly can make Avastar work better for you by adjusting the options in that panel.
The Add-on preferences contain various customization parameters for setting up the Avastar User Interface. You get to the Add-on preferences page as follows:
- Open the Settings Panel in the Avastar vertical tab
- Click the Avastar Preferences
The Add-on Preferences Popup
Note: All preferences have been documented by using long tool tips. Just hover over a specific element to see what it is about.
