Phong Material

Phong is the classic shiny material of early 3D graphics. The surface gets a smooth diffuse shade from the lights plus a bright highlight where a light reflects toward the camera. It is not physically based: there is no metal or roughness, just a color and a highlight you shape directly.

How it works

The highlight is the whole character of Phong. Shininess sets how tight it is: low values spread it into a broad glow, high values (up to 100) shrink it to a small hard point, like polished plastic or a glazed toy. The Specular color tints that highlight; the default is a dark gray, which keeps it subtle, and a lighter color makes it pop. Because the math is simpler than Standard, Phong is cheaper to draw while still showing a clear highlight.

Settings

• Color: the diffuse color (the default is a bright cyan).
• Shininess: size and sharpness of the highlight.
• Specular: the color of the highlight.
• Emissive and Emissive Intensity: a self-lit glow.
• Reflectivity: how much an attached environment map shows.
• Flat Shading: shades each face as one flat facet, the faceted low-poly look.

Use it for

Retro and early-game aesthetics, glossy plastic toys and objects, playful abstract shapes and scenes with many objects that still need a highlight. For a matte version with no highlight, use Lambert; for a realistic modern finish, use Standard or the plastic presets.
