A texture that crops out part of another Texture2D. [Texture2D] resource that draws only part of its [member atlas] texture, as defined by the [member region]. An additional [member margin] can also be set, which is useful for small adjustments. Multiple [AtlasTexture] resources can be cropped from the same [member atlas]. Packing many smaller textures into a singular large texture helps to optimize video memory costs and render calls. [b]Note:[/b] [AtlasTexture] cannot be used in an [AnimatedTexture], and may not tile properly in nodes such as [TextureRect], when inside other [AtlasTexture] resources. The texture that contains the atlas. Can be any type inheriting from [Texture2D], including another [AtlasTexture]. If [code]true[/code], the area outside of the [member region] is clipped to avoid bleeding of the surrounding texture pixels. The margin around the [member region]. Useful for small adjustments. If the [member Rect2.size] of this property ("w" and "h" in the editor) is set, the drawn texture is resized to fit within the margin. The region used to draw the [member atlas].
