How to get OnPostRender called after OnGUI.? URGENT

In my code Im implementing a custom control using GL in OnPostRender but it is appearing behind the GUI controls rendered in OnGUI, is there a way to change order?

 

Just change your OnPostRender method to a coroutine and use WaitForEndOfFrame as described in http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.OnPostRender.html

in c# you can write

Code (csharp):

1.  
2. IEnumerator OnPostRender() {
3.       yield return new WaitForEndOfFrame();
4.  
5.       // now you can do whatever you want
6. }
7.  

 

This is a very, VERY bad advice. Downright terrible. Starting couroutine every OnPostrender callback is insane waste of resources GC pressure and just calls for stutterfest.

Make a method with your GL draw logic and call it from OnGUI under event Repaint (and Repaint only) after whatever elements you need to draw it. Again, make sure you limit this call to be once per OnGUI because OnGUI called multipl;e times per frame. Repaint event called once per frame.
