Looking again at the promo I see the set is marked as being Trustyles and it is created by Truform, apologies for my confusion.

As I said there is a bow with the violin, in the prompo picture it is lead against the piano just behind the violin itself.  I did use this recently in one of my renders but I did have to tweak the texture before I was happy with it.

 

 

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.
