===PBS Skin Strength===
To maximize speed, the shader's fur layers use many lighting calculation shortcuts and approximations. The skin, however, can use proper physically based shading, which allows for more realisitic and accurate lighting effects.

Setting the PBS Skin Strength to 0 will cause the shader to use the same simplified calculations for the skin, which may be desireable in order to match the appearance of the skin and the fur in all lighting conditions.
