If you are a DAZ Studio user, you need the StudioCF installer. (CF means Companion File, btw..) Typically they contain optimized material presets for DAZ Studio, though I’ve seen lights and poses in the installer on occasion, but mostly you’ll find materials. The actual model files will be found in the Poser Format’s library.
The StudioCF files will install in your DAZ Studio Formats library. The Michael 4 Base StudioCF files are shown in the picture below.
PoserCF are needed only if you’re using DAZ content with the Poser program and the DSON importer for Poser. If you’re installing with DIM and only have DAZ Studio selected in the download filter, you’ll never see the PoserCF installers in your Ready to Download tab.
