The facing_ratio shader can also be used to achieve this shading effect.
A rim shader is useful for achieving a lighting effect related to the contour/outline edges of an object. This tutorial demonstrates a simple shader that simulates a fake rim light shading effect. It can be useful for creating fresnel or cartoon-like skin effects.

- A SamplerInfo node is connected to a ramp which determines the color of the rim light effect. This is connected to the base_color attribute of a standard_surface shader.
Rim shader network
- Changing the color of the ramp will affect the rim lighting effect. You can adjust the width and strength of the rim effect using a ramp texture.
