I'm working on an effect in which the users face gets a tan and reflects off light. Image the reflection being because they have an oiled skin. The user looks around and based on the angle the reflection will move around their face.
I've been trying to achieve this effect by making a face mask, adding a face mask material to which I've added a specular map. For that same layer I've enabled the Base Texture, Opacity Texture and Lighting. Together with a separate light source, to give the reflection, I've only been able to give the face a glow, but not that crispy glossy shine on the skin that I'm looking for.
I was wondering if anyone has had any experience with this sort of effects and how I could achieve this?
