To the best of my knowledge, IPB isn't intended to work with custom morphs. It is meant to work with the DAZ morph packs available for Vicki (or M3). Dark_Whisper released a program that would handle both custom and DAZ morphs here in the marketplace, but DAZ recently purchased all of DW's store content. I have no idea if DAZ will make Dark_Whisper's software available at some time in the future. The program was called Injection Magic.
