Can Unity's UI system create two or more independent Canvas GameObjects in your Scene?

Unity's UI system supports the creation of multiple independent Canvas GameObjects within a single scene. Each Canvas operates as a separate entity, allowing for both organizational benefits and performance optimizations. For instance, having multiple Canvases can help manage different UI states or sections of a user interface independently. This capability is especially useful in complex applications or games where different UI elements need to be updated or manipulated separately without affecting others.

Using multiple Canvases effectively can improve the rendering performance since Unity can batch draw calls more efficiently for UI elements that are on the same Canvas. Additionally, different Canvases can be configured with different settings such as scaling and rendering modes.

Thus, it is indeed true that Unity allows the creation of two or more independent Canvas GameObjects in a scene. This flexibility is an important feature for developers working on diverse UI layouts and interactions.
