The visual window is the visible area of the published content. Adding a visual window to a character and adjusting its size and position can achieve the effect of displaying only a part of the character after publishing.
Tick [Visual Window] at the top of the editors > click [Edit] to set the size and position of the visual window.
Note: If you want to import more motion for your character to the Mango AM, the size and position of the visual window must be the same as the first motion, otherwise the size and position of the imported character will be different.
