Suggest the great god of engineering：
Add a contour light map similar to the game, which is used to customize the shape or outline of the light.
A tool for drawing contour lines
Light map of contour lines
The generated lighting effect
Enrich the light map if you can.
R:contour lines>Control the intensity of light
G:ramp>Controls the intensity of the gradient.
B:ramp>Controls the tone of the gradient.
G and B Other parameters can also be controlled.
The above is one of my suggestions.
Thanks again for the great engineering god.
ps:
In addition, you can also add effects about subsurface.aitoon don't seem to have such an effect.
