zoom doesnt work on orthographic camera, while OpenGL projection is 3D

[10100010010001001010]

    camera = Camera::createOrthographic(1920, 1080, -1024, 1024);
    camera->setCameraFlag(CameraFlag::USER1);
    addChild(camera);

this is how I create my camera, and it does not apply the specified zoom, until I do this thing in my init scene function:
_director->setProjection(ax::Director::Projection::_2D);

I want to know if this is how I should do it, or if this is a bug in the engine code ? (or maybe I made a mistake somewhere )
As for the standard camera, when you increase the zoom, the culling starts to work incorrectly, and standard sprites are cut off before they disappear from the screen, while spine elements are displayed correctly.

Are you able to provide a minimal test case, screenshot or video of what it is you are seeing, and what it is you expect to see?

Do you mean culling?

[10100010010001001010]

yes, I mean culling. Look:


This is the default camera with setZoom(0.8). In the first image everything is fine, but as soon as you move the camera a little to the left, the image stops being displayed, although it is clear from its hitbox that the camera still sees it. With standard zoom everything is displayed as it should

if I try to use an orthographic camera, instead default, the zoom simply does not work, although I checked its value while the program was running and it was the same as I had set. As soon as I set Projection::_2D, everything starts working correctly. Including the display of this sprite with orthographic camera

yeah this is expected with zoom that is less than 1.0, I noticed it in axmol a long time ago and I think I fixed it for tilemaps but I don't know about sprites, the culling logic was flawed

@rh101, what do you think ?

Sorry, I don't have anything to add to this, since it's not an area I'm familiar with. I still strongly suggest that you create a sample project and post it somewhere, and perhaps someone can help when they can actually see the issue.

[DelinWorks]

have you tried calling setZoom on the camera object?

[10100010010001001010]

this is literally what I do next in my code, I just described how I create the camera, just in case

[DelinWorks]

call applyZoom

[10100010010001001010]

doesn't work. And besides, setZoom itself calls this method. I described the problem more accurately above.
