I normally credit a vendor if I upload to the gallery, as I was aware that the image appears in the Marketplace.  This is partly as a 'thank you' to the vendor and also in the hope it will give potential customers an idea of how it looks.  I know there are promos but I do think there is some value in seeing the results from an average user, an believe me I mean average.

If I make changes to the item I normally note that in the gallery description or do not credit.  Some of the vendors have commented on my images and which is think is great that they take the time an it implies at least that they like the way I have used it.  I don't expect every vendor to do that as I accept that they are busy, who isn't.  It is nice when it happens though.

 

 

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.
