"Your Character Setup file is invalid because there are controls in your file that cannot be found in your scene. This can be caused by loading an incorrect file, having namespaces on your controls, or possibly from changes to the character that have not been updated in your file. The following controls were not found in your scene:"
Attempting to load a Character Setup XML that does not match the rig in your scene, either because it is for the wrong character or some of the rig controls have changed. Also can be caused by attempting to load a Performance before opening your character in Maya/MotionBuilder/etc. The error will list the controls that cannot be found int he scene.
- Make sure that the XML that is being used is for the correct character and that it is updated if any controls to the rig are changed
- If using namespaces, the namespace must be contained in the XML file
- If using animation layers, you must be on the same animation layer where the XML file was created
