How do I make Unity's new UI render elements by Z-order?

I give up. I don't understand how sibling indexes, graphic raycasters, layer orders and the moon's position overhead combine to influence the arcane sequence by which UI elements get rendered.

Just tell me how to go back to a sane system based on Z coordinates.

Please.

 

I found the order that they appear under the canvas object in the editor affected (effected?) the render order.

 

As far as I know you can't do that. You could write your own scripts that translates z coordinates to sibling indices. But that means you still need to fully understand the current system.

If you describe cases for which you can't find a solution, I am sure you'll get help here in the forum.

 

OK, one of the many issues I'm having: I have two canvas objects and one will render behind the other no matter how much I fuss with the numbers of both.

 

Is there a reason both UIs cant be placed in one canvas?

 

What's the point of having multiple Canvas objects, then?

 

That is exactly how they are supposed to work.

 

Got it. "Screen Space - Overlay" and "Screen Space - Camera" do not mix, and if an object is in "Screen Space - Overlay" it won't render child meshes. So everything has to be Overlay.

Dantus: Yeah, what I meant is, Canvas A would render behind Canvas B no matter what values I inputted on either. This turned out to be because of the Overlay/Camera discrepancy.
