Ior to specular
WebControls the glossiness of the specular reflections. The lower the value, the sharper the reflection. In the limit, a value of 0 gives you a perfectly sharp mirror reflection, while 1.0 … Web1 aug. 2024 · The default ior is 1.5, which gives you 0.04 (4% of light reflected at 0° angle for dielectric materials). F0 values lie in the range 0-0.08, so that’s why the default F0 …

WebSpecularity refers to the amount of specular light reflected by a surface. This value is inherent to the Material type, and usually the default value of 0.5 is accurate. The Specular input is not used for reflection/specularity maps or to add surface variation. These should be handled in the Roughness map. Metallic
