I reiterate, have someone look to see if the problem is associated with the PrincipledVolume node.  That is the only major change that was introduced into Poser 13.1.518.

Actually the issues already started with the update from Poser 13.0.339.0 to Poser 13.1.449 meaning if the PrincipledVolume node is introduced  in 13.1.518 then it is not the cause, it is something that changed between 13.0.339.0 and 13.1.449 ......

ok it has been added in Poser 13.1.432 - 2023-08-03 - Hardware Preview works better with Cycle shader plus Principled shader node but many other changes also happen ....

I am sure they will find the cause and break something else :) I tip on gamma and pixel shift that was causing problems since the beginning ....
