Unity multiple canvas in scene

Like many other game engines, Unity is known for continuously expanding, and it has evolved drastically over the years. In particular, Unity 5, which was published inbrought a lot to the Unity community.

It mentions that each Canvas is an island that manages and groups all the geometry generated under it. So changes to any of the renderable UI stuff under it makes it have to recalculate the geometry for ALL the possibly-thousands of renderable stuff— which they mention, can cause noticeable multiple-millisecond CPU spikes. Realistically speaking, this may not be a problem if your UI is really simple but you can imagine that it can get unnecessarily wasteful as you make it more and more intricate. So having one giant Canvas for your whole UI is not recommended by Unity. And especially where performance is super important, separate the UI parts that get updated a lot from the parts that stay mostly static.

The Canvas component represents the abstract space in which the UI is laid out and rendered. A single Canvas for all UI elements is sufficient but multiple Canvases in the scene is possible. It is also possible use nested Canvases, where one Canvas is placed as a child of another for optimization purposes. A nested Canvas uses the same Render Mode as its parent. Traditionally, UIs are rendered as if they were simple graphic designs drawn directly on the screen. That is to say, they have no concept of a 3D space being viewed by a camera. Unity supports this kind of screen space rendering but also allows UIs to rendered as objects in the scene, depending on the value of the Render Mode property. In this mode, the Canvas is scaled to fit the screen and then rendered directly without reference to the scene or a camera the UI will be rendered even if there is no camera in the scene at all. If the screen's size or resolution are changed then the UI will automatically rescale to fit. The UI will be drawn over any other graphics such as the camera view. Note: The Screen Space - Overlay canvas needs to be stored at the top level of the hierarchy.

In Unity, this often translates to heavy scenes with a big amount of GameObjects.

The Canvas The area that contains all UI elements in a scene. The Canvas area is shown as a rectangle in the Scene View. More info See in Glossary component represents the abstract space in which the UI is laid out and rendered. A single Canvas for all UI elements is sufficient but multiple Canvases in the scene A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary is possible.

If you need to create large streaming worlds or want to effectively manage multiple scenes A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary at runtime, you can open and edit multiple scenes in the Unity Editor simultaneously.

If this is not used then the UI may disappear from the view. However, if something like this is going to hamstring performance right out of the box, that worries me. A nested Canvas uses the same Render Mode as its parent. The size of the Canvas can be set using its Rect Transform but its onscreen size will depend on the viewing angle and distance of the camera. A single Canvas for all UI elements is sufficient but multiple Canvases in the scene is possible. The entire point of me doing these courses is to be comfortable with a base skeleton to make an RPG. Good looking out. Unity supports this kind of screen space rendering but also allows UIs to rendered as objects in the scene, depending on the value of the Render Mode property. If this is not used then the UI may disappear from the view. In particular, one key feature that we are developing to address the ever growing pains of collaboration for game projects is conflict-prevention. It is also possible use nested Canvases, where one Canvas is placed as a child of another for optimization purposes. Suppose you have an audio manager script that should be loaded when the game first starts, and then is used throughout all the levels to play music or sounds. Because using events is a great way to completely decentralise logic, and remove dependencies.

Realistically speaking, this may not be a problem if your UI is really simple but you can imagine that it can get unnecessarily wasteful as you make it more and more intricate.

Child canvases also isolate content from both their parent and sibling canvases. Suppose you have an audio manager script that should be loaded when the game first starts, and then is used throughout all the levels to play music or sounds. Diversion is a cloud-native SCM solution that allows all team members - developers, designers and artists - to use a single, simple-to-use version control system. Unlike Screen Space - Camera mode, however, the plane need not face the camera and can be oriented however you like. The size of the Canvas can be set using its Rect Transform but its onscreen size will depend on the viewing angle and distance of the camera. Good to know. A single Canvas for all UI elements is sufficient but multiple Canvases in the scene is possible. Indeed, by splitting your scenes in a smart way, you can effectively have the project organisation follow your team organisation, and use this feature to divide your tasks and avoid asset conflicts. So, no worries. Another nice application of multi-scene editing is for data, and more particularly for global game data at the session-level. Plus, it requires you to mix a lot of areas of expertise - be it 2D art, 3D modelling, scripting, level design, story and dialogue writing….
