The MVadapter portion of Micmumpitz consistent character sheet workflow. I saw a number of folks complaining about the MVadapter portion not working, I had similar issues the 1st time I tried using MIcmumpitz's workflow and it turned out that he had more than one diffusor node packages incorperated in the workflow. Some of the ouput noodles had tags that looked the same but were actually different and caused runtime issues in ComfyUI.
This workflow is the bare minimum to use MVadapter.
