So...
The readme says its ok to share the pcf-files but no mention of the cr2 and othe files contained in the ZIP.
As the CR2 (as stated in the readme) contains morphs from other artists it may not be legal to distribute, maybe someone else here can give their opinion on this.

The pcf-files let you create OBJ-files but that only gets you half the way, I guess you could edit a copy of the original dork cr2 to point to the newly created 4DukeM3.obj               and P4DukeAlternateHip.obj

I asked an AI what we can do if we only have the OBJ but are missing the CR2. The process actually sounds pretty straightforward. Could you share the .pcf file with us?

1. Copy the original: Locate the original Dork.cr2 in your Poser Runtime folder (Runtime/Libraries/Character/...).
2. Duplicate & Rename: Copy this CR2 file into the same folder and rename it (e.g., Dork_Modified.cr2).
3. Open in a Text Editor: Open this new CR2 file using a plain text editor (like Notepad++ or standard Notepad). CR2 files are just text documents.
4. Find the OBJ reference: Search the document (press Ctrl + F) for the keyword figureResFile. Next to it, you will see the file path pointing to the original Dork OBJ (usually located inside Runtime/Geometries/...).
5. Replace the path: Change this path so it points exactly to the location and filename of your new, modified OBJ file. (Important: This reference usually appears twice in the file – make sure to update both entries).
6. Save: Save the file. When you open Poser now, the new CR2 will automatically load your modified mesh while instantly keeping all the bones and joint parameters from the original figure.
