In Unity, what is a common reason for using the Specular workflow?

The Specular workflow in Unity is commonly used to achieve realistic metallic surfaces within materials. This workflow emphasizes how surfaces interact with light, specifically how they reflect light based on their material properties. In this workflow, the specularity of the material is defined, allowing developers to control the intensity and color of the highlights seen on materials, particularly for metals. By using this approach, artists can create a convincing appearance of metallic surfaces that responds appropriately to light sources in the environment, enhancing the visual realism of 3D models.

This method contrasts with other workflows, which may focus on different aspects of material appearance or are oriented towards different use cases, such as 2D efficiency or non-metallic surfaces. Emphasizing realistic metallic rendering makes the specular workflow particularly valuable in scenarios where achieving a lifelike representation of materials is essential for the overall aesthetic of the game.
