Why is my PBR 3D model too shiny?

Your PBR 3D model is too shiny usually because the metallic value is too high, the roughness value is too low, or the scene lighting is overly intense or misconfigured. Metallic controls how reflective the material is—higher values mean a more metal-like, shiny surface. Roughness affects light diffusion—lower values make surfaces smoother and glossier. Harsh or bright lights can also boost shine even if materials are set correctly. Try lowering the metallic value slightly, increasing roughness to add subtle texture, or softening scene lights (e.g., using area lights instead of point lights) to reduce excessive gloss.
