How to light the back of my models without adding extra light?

Questions & Answers

In my scene I have one directional light that is attached to the camera and points in the direction that the camera is viewing. The problem I have is that for some objects in my scene I get a dark face that isn’t getting hit by light.

These objects are using mobile diffuse shaders and they are not static (motion done through modification of the transform, not physics).

How can I light the back of these objects without adding an extra light to my scene?

Well, if you don’t want to explicitly add a light to your scene, your only other option is to increase the global ambient light. Edit → Render Settings → Ambient Light
