Particle and render Q

[iwishash]

Hi,
I upgraded my project from 2.7 to 3.0.7 f1 and changed all of my panel's z depth to panel depth to draw correct order. (hard work )
But it's not worked for non NGUI widget. The Unity particle objects.
I couldn't see particle above UI.
I read new documentation of UIPanel.
There's article about Render Q option. It seems the function what I wanted.
But..give me just more information to follow.
The particle object located in my panel A.
I made another panel B for particle and moved particle objects to here and set the Render Q option to "Start At" with 3001 value.
Nothing changed.
Other setting (Explicit) was same as well.
What did I wrong?

NGUI won't change particle systems for you. That's something you need to do yourself. If you know that your particle system is drawn with a render queue of 3000, set your panels to render queues above or below it accordingly.

I suggest creating a custom shader for your particle system where you set your own render queue explicitly.
