I don't know if this is the right place ..., but using Poser 11.
I often see products that I like but only for DS. I would like to import them as objects and therefore as prop ..... But I'm not familiar with .duf files.

I actually have DS installed and then export from there.

There is this script https://www.renderosity.com/rr/mod/bcs/duf-prop-converter-for-poser-12/153019/ but it's for P12

Thanks RedPhantom, Unfortunately I work on Mac ...:(

The only way I can think of is to actually use DAZ Studio to export as an OBJ. It has an option to export as Poser Scale.

DS to Poser, 11 or 12: no problems with some items.
For Stonemason's villa I've exported in Collada format, retrieved the bitmaps and setup the materials to use Cycles in Poser.
For other items, I had to use the FBX format. Once again, I'm used to rebuild the materials as most of the time, what I buy for Poser is using old setups, except for a few awesome vendors which are creating the right materials directly.

The choice between Collada or FBX depends on the fact that, depending on how it is thought and setup, you may retrieve everything posed as the coordinates (0, 0, 0) using Collada, but when it works, it's cool and more stable: the problem with FBX is that each program seem to have its own version, that's particularly weird when its Majesty Blender itself sends you to strawberry fields, saying something like "Nah... FBX too old, I refuse"

I prefer DSF Tools, but that struggles with high-poly meshes, does not provide an MTL and often mangles complex scenes.

Although DS' UI gives me a prompt migraine, here's my recipe for using that route...
