Odd Sorting Problem

[artician]

I have two UI's in my scene.  They're separate from one another, but I have their depths set so one should draw over the other, (acting as a popup dialog for user messages and help).  The problem is that it draws behind everything, all the time. 

It doesn't seem to matter how close I move the UI to the camera by hand, or what value I set its components depth to, the UI I want on top is *always* drawn behind the other one.  What would cause such a thing?

Here's a screenshot of the scene, but I had to crop it close because I can't show the work.  :/ 



I hope it's enough for someone to tell me what's going on at least.

Make sure you set the depth of the UI cameras.

Doesn't make any difference, unfortunately!

Any other suggestions?  Thanks for the reply.

I figured it out.  I had all my gui cameras using the same layer.

Thanks for the help.
