Hi ,
I downloaded a script Bake Under Parent from creative crash. My maya version is 2012. When I execute it in the script editor nothing happens.

After that when I run it through command line by its global proc name it runs properly.

If I reopen maya and directly type the global proc name it gives an error (Cannot find the procedure 'bake_under_parent')

Kindly Let me know where lies the problem

Thank You user added image

When you execute lines like..

Code:

global proc Gen_printThis(){
	
	print "This is a test!\n";
}

in Maya, you are simply defining the global procedure. Now Maya knows it exists so you can now call on it with..

Code:

Gen_printThis;

However, restarting Maya flushes all that info from memory, hence the error when calling the script.

If you don't have a "userSetup.mel" in your scripts folder, now is a good time to make one, it runs mel commands on startup and you can have it source the mel file. Close Maya. Create a .txt file in notepad or whatever, type...

Code:

source theNameOfTheMelFile;

Close notepad and change the .txt extension to .mel. Now Gen_printThis can be run and Maya already knows where to find it. This comes in especially handy when multiple global procs are in one file.

You can even drag

Code:
