The Curvature shader is an easy way to add detail and realism to your shaders. In this short tutorial we will use the Curvature shader to create a wear and tear shading effect. It will be used to represent where the edges of a hard surface are scraped on the model of a mech. Notice in the image above how the edges of the paint appear worn off, exposing the metal underneath.
- In the example images below, the Bias parameter of the Curvature shader has been increased and exaggerated to better demonstrate the effect.
- Increasing the number of Curvature samples reduces noise and gives a better quality result.
