Autodesk Maya Error: setParent: object ‘renderView’ not found

If you get an error like "renderView not found" when you hit render button, open the MEL Script Editor, then write and execute the code below:

 Turkish: 
Eğer Maya'da render tuşuna bastığınızda başlıktaki gibi bir hata alıyorsanız MEL Script Editor'ü açın, aşağıdaki kodu yapıştırın ve çalıştırın:

$exists=0;
 for ($item in `getPanel -scriptType "renderWindowPanel"`) {
        if ( $item == "renderView" ) {
                print "renderView exists.\n";
                $exists=1;
        }
 }
 if ( $exists == 0 ) {
        for ($item in `getPanel -scriptType "renderWindowPanel"`) {
                //print ( $item + "\n");
                if ( $item == "renderWindowPanel1" ) {
                deleteUI renderWindowPanel1;
                $renderPanel = `scriptedPanel -type "renderWindowPanel" -unParent renderView`;
                scriptedPanel -e -label `interToUI $renderPanel` $renderPanel;
                }
        }
 } 

This should fix that.

İyi çalışmalar.

Autodesk Maya: Help Line Becomes Unresponsive

Sometimes when working with Maya, Help Line might become unresponsive. That's one of the billion bugs of Maya. To fix that, just select and move (undock) the Help Line window then dock it again. This will refresh the Help Line and it will work again. 

PS: I tried this on Maya 2012. Don't have an idea for other versions but it should work on other versions too.
