Soft Front Lighting should look roughly like the following example. While shadows still exist, they are minimal and not harsh. The characters are still plenty bright and normally saturated, which allows the engine to tint them, desaturate them, or darken them as needed to match the environment.

This lighting type can be used (with applied tinting) for outdoor nighttime shots, for indoor shots in rooms without artificial lighting, and for shots standing behind those who are seated around the fire (but not seated themselves), in other words, shots where they are not close enough to have the harder front lighting of the fire applied to them.
