You need to add this code somewhere (maybe converted to Python) to make sure the correct MEL scripts have been sourced. if (!`exists artBlendShapeSelectTarget`) { // *Properties.mel and *Values.mel are MEL scripts to fill in the tool settings window for a context. // The MEL proc you're looking for is defined in one of those files, but none of it has been sourced yet // so Maya doesn't yet have it available. Source the *Properties file and it should source all the other // files you need. source artAttrBlendShapeProperties; } -Tim -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
