The only drawback that I have found in EZSkin3 is the inability to activate the SSS material settings for the skin textures.  There is no check box option.

@ Y-Phil: I don't know if this is an option that can be easily implemented, and it would be appreciated if you have some time to look into it.  I think it is a feature that should be available to users as an option rather than an assumption that it is already activated when EZSkin is applied.
