-				Returns the viewport's texture.
+				Returns the viewport's texture. Note that due to the way OpenGL works, the resulting [ViewportTexture] is flipped vertically. You can use [method Image.flip_y] on the result of [method Texture.get_data] to flip it back, for example:
+				[codeblock]
+				var img = get_viewport().get_texture().get_data()
+				img.flip_y()
+				[/codeblock]
