The correct sequence is to run the script prior to opening Poser. You will not, and should not, see anything happen other than the script run. This should be a one-time event as an initial set-up, however, every time you load a new morph package, you must re-run the script. Open Poser, load Michael 4 into your scene, then go the folder containing your morph package(s) and either drag and drop or double click the morph to load into Michael 4 making sure the figure is selected. Your morphs will appear in the parameters/properties panel and all you need to do is dial-up/down the morph for Michael to physically change. The purpose of the script is to generate additional channels for all the morphs to load correctly and work.
