Shader artist question ? (reflection)

Hi everyone,

How this is realized?

The light source is in front of the cam. Some areas did not reflect light. Other areas receiving lights but from different sides. I have no clue how this can be done by normal, specular or smoothness.
Any ideas or solutions?

 

It could be a point or spot light with limited range. https://docs.unity3d.com/Manual/Lighting.html or perhaps a custom shader with falloff.

 

I think the specular\reflection\emission gbuffer channel for a realtime lights is changed by any vector normal Map calculation or perhaps a bloom function.

The direct light Emission\Reflection is far wider than a point light. Something between an area and point light.
