I have the Silo official guide and a large number of the Digital Tailor tutorials on sale here at Renderosity.  The book is useful but I find the tutorials so much easier as I can see on screen just what the model should look like in Silo.  

The early tutorials cover getting your models into Poser where applicable.  On the rare occasions I needed to contact the creator, Fugazi1968, I always recieved a quick and supportive response.  

Not only am I beginning to learn Silo I am also creating models I can use in Poser and creating templates to model from so I can't think of a better way of learning a program.

 

 

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.
