How to get projected content rendering at the correct zIndex within a 2d scene?

[nous-]

I am attempting to render 3d content with pixi-projection at a target zIndex within a 2d scene, but the zindex is not being obeyed, and the 3d content is rendering over the entire scene.

const background = new PIXI.Sprite(backgroundTex)
background.zIndex = 0;
stage.addChild(background);

const camera = new projection.Camera3d();
camera.setPlanes(500, 30, 10000);
camera.zIndex = 1;
stage.addChild(camera);

const sprite = new projection.Sprite3d(spriteTex);
sprite.euler.x = -20 * PIXI.DEG_TO_RAD;
camera.addChild(sprite);

const foreground = new PIXI.Sprite(foregroundTex);
foreground.zIndex = 2;
stage.addChild(foreground);

stage.sortChildren();

Hello!

that's no way someone answers on pixi-layers on stackoverflow.

pixi-projection on itself doesnt have 2d zIndex, and it doesnt have 3d z-buffer going on.

pixi-v5 has zIndex inside container if you specify container.sortableChildren = true

pixi-layers uses different variable - zOrder, and you have to actually look its README instead of just smashing random pieces of code

Also, all 3d stuff must be put in camera.

I've since got the camera correctly rendering at the correct zIndex using the same code above. I blundered in my work by having it on the wrong layer and thinking in the same coordinate frame as sprites. Thanks for the slack discussion.
