I am using Silo and have purchased and worked through a number of the tutotials here at Rendo by Fugazi1968 who uses Silo for most of them.  There is one tutorial in Prime, if you are a Prime member and, if not, the tutorials are on sale at the moment.

I found Silo easy to learn, at least the basics, and while I generally have little success learning, particularly by reading, I found the tutorials a great help as I was able to see what Silo looked like in the video and match it to my model in Silo itself.

Tutorials or not, if you want to start doing some modelling I would say it is a steal at $20.

 

 

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.
