Now I am going through the last quadruped tutorial video no.5. Everytime when I tried to press the button “create/modeify/matchRig” after I had some modifications of the controls position, I would have the following error message. I am doing this test with the Biped Autorig. Does anyone know why this happens? How can I avoid this error?
thanks for your attention!

Error running callback:
global name ‘animparms’ is not defined

Please try upgrading to a version of Houdini 9.1 greater than build 135. This error is caused by a bug introduced when doing a fix for the large amount of changes that happened to asset parameters.
