"Just curious but what is it about vue that does not render skin tones well ??" It has no scattering option, that I've seen, in it's materials. Skin scatters light, and representing that in renders makes it look more real. Face_Off's real skin shader, for example, provides a fake SSS node structure for "scattering" forward light, and the fastscatter node can be used for scattering backlight. Used together, the reasults can be almost as good as a subsurface scattering material. Edit: I see in the Vue forum, someone came up with a way to fake this using Vue shader system now too... but only for forward scattering... not backlit scattering. Also, Vue doesn't have blinn specular shading, that I know of, which is a way to more realistically represent skin highlights.
