Quote - You mentioned that nothing has changed between updates, however you have not provided enough information to go by.  What are your render settings?  What type of lights are you using?  Is IDL involved?  Are you using Gamma correction?  What is your min shadow bias on your lights?  Are you picking up active ambient lighting in your material?

 

Thank you for your input and I do understand that all of the factors you mention do have an impact and that by adjusting them I can almost certainly get back to where I was.  My point is that all the factors you have listed are the same as they were in 2012 before I installed SR1. According to the release notes the SSS is now more stable and more robust but it appears to have changed the results quite dramatically.  I will continue to work on the problem but I just wondered if someone else had noticed the change and already knew the fix.

 

 

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.
