Clearcoat GGX is a shading model used in physically based rendering (PBR) to simulate how light interacts with the microfacets of a clearcoat layer. It produces realistic, high-gloss reflections that sit on top of the base material, allowing smooth, polished highlights even when the underlying surface is rough. It delivers natural-looking edge highlights and reflection falloff, enhancing the sense of depth and realism in coated surfaces.
Use cases include:
- Simulating glossy coatings on metals, painted surfaces, automotive finishes, and plastics.
- Adding a reflective top layer independent of the base material’s roughness for greater visual realism.
