Victoria 4 materials on Genesis 2 Female
If you use the Victoria 4 for Genesis 2 Female product to enable the use of character maps for Victoria 4 on Genesis 2 Female you will need material files that are in .duf format, rather Poser-format .pz2 or .mc6 files or DAZ Studio .dsa or .dsf presets. If those are not provided conversion is a simple process.
Ideally, you should load Victoria 4 and apply the non-.duf preset you want to convert to the figure - you can use the original Genesis if you don’t have Victoria 4, but you will lose any settings for the transparent eye surface (often used to provide reflections). Having applied the textures to Victoria 4 go to File>Save as>Materials preset, pick your save location and name (e.g. People>Genesis 2 Female>Materials>Victoria 4 Textures, Marie-converted.duf) and then click Accept on the options dialogue. You should then be able to find the saved files in the Content Library pane (e.g. under DAZ Studio Formats>My Library>People>Genesis 2 Female>Materials>Victoria 4 Textures).
