That particular set comes with the UV templates as part of the package, as do the other sets in the same range.  Also they are split into a large number of material zones which are well named making it easy to identify the parts of the model.  If you are unsure of the parts represented by a material you can always make the material bright red or some other distinctive colour in the material room and then undo the changes when you have identified the parts.  That said I did not need to do that with this set.

You can make the crafts look very different from the standard just using other materials but if you are good in Photoshop the UVs should help.

 

Above is one I prepared earlier...ohh and I have no interest other than being a happy purchaser of many items from the same vendor.

 

 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
