Scene Panel
The Scene panel is the central work area for content creation, used for selecting and placing scene images, characters, effects, UI, and other game elements. This workspace allows to select and modify the position, rotation, and scaling of nodes with the Transform Gizmos, and get a WYSIWYG scene preview.
View Introduction
The Scene panel includes two views, 3D and 2D. The 3D view is used for 3D scene editing, while the 2D view is mainly used for editing 2D elements such as UI nodes, etc. The scene view can be switched via the 3D/2D button in the toolbar at the top left of the editor.
