The cocos sub-camera does not display the problem that the dual cameras do not display and cannot be displayed at the same time

The cocos secondary camera does not display the problem

For example, the ui effect we normally want

 

But it became like this

 

It is because your two attributes are not adjusted properly

That is, the Priority and Visibility of the Camera

 

 

Priority means priority, to see which camera is displayed first

If the value of the main camera is larger than that of the auxiliary camera, the content of the main camera may block the auxiliary camera

For ClearFlags

ClearFlags means how to display other parts in addition to the normal display

If it is SolidColor, it is a solid color, which will block the content of the main camera

So we're going to modify

For 2d, as long as you don't declare solidColor, there is generally no problem

In fact, each is literally

dontClear means no clearing at all, whatever is available in other parts of the camera

DepthOnly should only look at what is at the right depth, but it seems not very accurate

Skybox is to fill in the blank box, it is estimated to be used for 3D

But for this 2d project of mine, all three are the same.

It is recommended to choose dontClear

Take a look at the official documentation for details!
