ok I have this really strange problem that I get quite often and now Iīm very tired of it. And because I get this problem quite often, atlest someone here should know what the problem is! It has happend both the times I have animated a character lifting a box, because then for a couple of frames, the arm is very stretched. Then I realize that the arm is stretched(like a straight line) all the time and I canīt stretch it back to normal!

does anyone know why this happens? would help me so much!

thanks/jimmy

Hi,

I think I have a solution to your problem. That is if I understood it correctly.
There is a bug in one of the maya scripts that get accessed when you right click on top of a joint. It always executes the set preferred angle command for whatever joint you have selected. It makes no difference if you select the pop up menu to trigger the command.

The way to fix this is to modify the following script:

dagMenuProc.mel


menuItem -l "Set Preferred Angle"
-echoCommand true
//-c `evalEcho($setCmd)`
-c $setCmd
-rp "N"
setPrefAngleItem;
menuItem -l "Assume Preferred Angle"
-echoCommand true
//-c `evalEcho($assumeCmd)`
-c $assumeCmd
-rp "S"
assumePrefAngleItem;


I hope this does the trick for you.
