How to fix too shiny in UV maps 3D models?

To fix excessive shine in UV-mapped 3D models, adjust the material’s specular intensity or roughness properties (common in software like Blender, Maya, or Substance Painter) to reduce light reflection. Shine stems from material-light interactions—not the UV map—so lowering specular (direct light bounce) or increasing roughness (scattered reflection) reduces gloss. If you use a specular/metallic texture map, edit it to dim overly shiny areas. For a quick Blender fix: Go to Material Properties > Surface, drag the “Specular” slider left or raise “Roughness” until the shine feels natural.
