Or in the case of a legacy preset in the Iray shaders for a character (or possibly other item) they are settings for Iray in DS 4.8, where there was a bug fix in 4.9 that changed the way SSS rendered.
No, the settings would generally not work as well - I'm not sure if they would overwrite the later files, that may depend on the way the product was set up.

legacy files are for older versions of DS
Or in the case of a legacy preset in the Iray shaders for a character (or possibly other item) they are settings for Iray in DS 4.8, where there was a bug fix in 4.9 that changed the way SSS rendered.
So should I install legacy files for DS 4.20? What would happen if I installed them over the newer files?
