Matte/rough vs. glossy/polished
Show how matte, rough surfaces scatter light and glossy, polished surfaces produce sharp highlights and clearer reflections.
What it is
Surface roughness changes how light behaves. Rough, matte surfaces scatter light, producing soft, low-contrast highlights. Glossy, polished surfaces focus light into small, sharp, bright highlights and clearer environmental reflections.
Match highlight size, contrast, and placement to the material. Matte surfaces such as hoodies, rough stone, and unpolished clay can have broad, subtle highlights close in value to the base color. Polished boots, ceramic mugs, and lacquered tables can have tight, high-contrast highlights near the brightest value.
Adjust edge sharpness and texture with the surface quality. Matte surfaces use softer transitions between light and shadow, while their texture remains visible in lit areas. Glossy surfaces use sharper light-to-shadow transitions, and strong highlights can obscure local texture.
Why it matters
This distinction helps separate materials such as leather, skin, stone, metal, rubber, and ceramic. Weak control gives different surfaces similar highlight shapes, sizes, and strengths, making forms harder to read.
You can check it when
- ✓Paint one simple shape, such as a sphere or cube, as both chalky and matte and polished and glossy without changing its base color.
- ✓Vary highlight size, sharpness, and intensity according to the material.
- ✓Keep broad, subtle highlights and visible texture on matte materials, without adding random shiny spots.
- ✓Use crisp, high-contrast highlights on glossy materials, with placement that follows the form consistently.
