Z depth of placing 3d model c3b is ignored addChild(modelc3b,3); or addChild(modelc3b,-3) are the same

• devices test on: Windows
• developing environments
  • Visual Studio: 2022
    Steps to Reproduce:

1. Add in hello world example

auto sprite = Sprite::create("HelloWorld.png"sv);
    if (sprite == nullptr)
    {
        problemLoading("'HelloWorld.png'");
    }
    else
    {
		
        // position the sprite on the center of the screen
        sprite->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y));
        // add the sprite as a child to this layer
        this->addChild(sprite, 0);	
        
    }
	
    // add tortoise.c3b
	auto modelc3b     = MeshRenderer::create("tortoise.c3b");
	modelc3b->setScale(0.2f);
	auto s = Director::getInstance()->getWinSize();
	modelc3b->setPosition( Vec2(s.width * 4.f / 4.f - 530, s.height / 2.f) );
	// here second parameter od z_depth DOES NOT SENSE AT ALL I was triyng 0, -1, 1, -3, 3 ....
	addChild(modelc3b,3)

Doesn't that only affect the local Z ordering on a specific layer for 2D?

The global Z value should work. Try setGlobalZOrder.

Yes this `setGlobalZOrder works !

Thankl you! You are very kind!
