Softer shading from light?
Is it possible to get some more control over shading, something like this; (Video). What I'm talking about is the 'Shade Width' and 'Lighting Bias' shown between 0:10 - 0:27 I mainly want to be able to control the bias for my purpose.
I did play around with different lights but couldn't really find anything so unless i missed it what would be the best way to do this? material, post process, Light function, or maybe there are console commands for this? surely this can be changed somehow (fingers crossed)

Hello again Creamshake,
I do see what you are talking about, however what you are attempting to change is not really how a light would function on a mesh correctly. The "normal" image is how the character shadows would be accurately represented when being lit with a directional light.
Along the same lines as that, what you are attempting to do is have a global light, your directional light, on an individual object cast shadows differently than the rest of the objects in the scene. With how forward rendering works, that would not be possible, nor would it be very efficient if every object was able to have its own shadowing calculations. This would become a very expensive process on the engines processing.
There are work arounds to reduce this shadow firmness such as changing the characters material, decreasing the light's intensity, and using the RayTraced Shadow Technique mentioned earlier. Here is an example of how the intensity of the light is affecting this shadowing.
Firm Shadows with Intensity at 20.0
Softer Shadows with Intensity at 4.0
I hope this helps clarify your question.
