Open another Scene in a UI-Element

Hello
I need help to make the follow situation with 2 scenes at the same time.

I have 3 "Overworld"-Scenes in which the character can move.
And I have a Scene D that can be called in the player menu.
The camera view of the fourth scene should be visible in a UI element as in the following figure.


How can I do that?
The scene D with his objects should not appear in the "Overworld"-scenes. (no Overlap)
I want 2 different scenes with an own camera.
This camera-sight should be visible on a UI-Element.
(Both scenes are independently and active at the same time after the call from the menu)

How can I show the camera image of scene D on the UI element?

How can I open a new scene at the same time without overlapping ?

look forward to your help,

greetings

andy

Do you mean keep all these scenes running at once? That is totally possible but will require you to organize them in a way that lets you:

- load them all concurrently (either positionally offset or else layers-offset)

- easily control and enable/disable the cameras coming from each one, as well as adjust their rectangles and layering

Iterate, start small, try to get a second scene running and overlay its camera in a first scene. It's totally doable, it just requires a lot more setup and connections to maintain.

 

Thanks for your answer, but I meant it differently:

I explain it more simply:

I wanted to load 2 different scenes at the same time.
they run in different "coordinate areas" (= independent coordinate area / spaces)
(= The objects in should stay in their original scenes and not appear in the other scene.)

And I want the camera view from the camera in the second scene on a UI element in the first scene

 

You can load your scene additively (keywords: LoadSceneAsync + LoadSceneMode.Additive)
You can have everything in the additive scene on a particular layer. Your second camera can set to render only that layer and to a RenderTexture, your main camera should exclude that same layer, so the things in the second scene won't show up.
That RenderTexture then can be projected on a RawImage component.

Be careful, this method can be costly in terms of resources.

 

Thank you,
that's a good idea

 

Ah yes, even easier, and as Lurking says above, additive scene loading is your friend, then layered cameras.

You can perhaps see considerations for this by looking up "security camera" tutorials. That lets you even put the distant scene onto the front of a diagetic object, such as a television monitor in your current scene.
