It's kind of hard to see the sorting since your planes use an alpha less than 1, but you're doing this the right way. To sum it up:
1. make ObjectContainer3D 2. make Plane and addChild to the ObjectContainer3D 3. Change Z of Plane 4. Change rotation of ObjectContainer3D That'll give you fully working sorting + simple to adjust/position planes. Rather than rotating all the planes, it's also easier to just let the planes stand still and move the camera. J
