Ior to specular
Web20 nov. 2024 · Metalic is set to 1 and specularity to the value above the sphere. It's a very subtle effect, but the way the principled shader is designed, it is in effect using the IOR of a material to simulate the Fresnel effect. It, in fact, implements a variant of the Fresnel equation to accomplish the transition between specular and diffuse. WebTo control the strength of refractions, you adjust the IOR parameter. But notice that IOR is in the Specular section not in the Transmission section, which deals with transparency. …

WebSpecular controls how much light a surface reflects and the color of the reflection. In UE4 when you set metalness to 1 it will use the value/color in your base color as the specular, but when you set it to 0 it sets a default value that you have no control over.
