Which two workflows can be used to make an object look metallic with the URP/Lit Shader?

In the context of the Universal Render Pipeline (URP) and the Lit Shader, achieving a metallic appearance on a 3D object primarily involves utilizing the appropriate workflows designed for rendering materials correctly.

The metallic workflow is specifically designed to handle metallic surfaces, allowing artists to differentiate between metallic and non-metallic surfaces effectively. In this workflow, the material's metallic property can be defined, affecting how light interacts with the surface, resulting in the characteristic shine and reflectiveness associated with metals.

On the other hand, the specular workflow allows for a more traditional approach to defining how light reflects off a surface. While it can be used to create the illusion of metallic surfaces by modifying the specular values, it does not directly encapsulate the unique properties required for rendering pure metallic surfaces as effectively as the metallic workflow.

Together, the metallic workflow provides a more accurate physical representation of metals, while the specular workflow can be employed to enhance the visual effects on materials that may need a specific reflectance value.

This combination enables developers to choose the best approach for their material design needs within the URP, leveraging the capabilities of each workflow for optimal results in visual fidelity.
