Close Your name Your email Suggestion* DescriptionAn instance of this class holds a tree of VisualElementAsset's, created from a UXML file. Each node in the file corresponds to a VisualElementAsset. You can clone a VisualTreeAsset to create a tree of VisualElement's.
Note: You can't generate a VisualTreeAsset from raw UXML at runtime.
The following example loads a VisualTreeAsset from a UXML file in a custom Editor script.
