Maybe. I didn't get yet to play with specular term, current one is just vanilla Phong.

There should be still some performance margin left, I tried to tune it to keep 60 fps on my notebook.



And it's done, if you clear cache and reload, it should be using physically based specular term.

Visual difference is quite subtle - skin feels more "silky" and ears are more shiny.

No noticeable degradation of performance.
