Hello! We just made some good updates to Malcolm 2.0. All expressions removed and replaced with math nodes for speed and stability with newer versions of Maya. Much better ik/fk snapping, switchable space switching attributes on the arm ik controls (make them follow the chest/head etc and keyable on attributes), fixed a few shaders and outfit bugs. You have to use the new body picker with it for the new features to work.

You can download it here. If you are already animating a scene, you can swap the reference for the new file.
