WebBling-phong often uses the term shininess for the specular power. You essentially want to map a roughness of 0 to some very high shininess (say 10000) and 1 to some very low shininess. In the past, I've used: shininess = 100/ (500 * roughness + 0.01) and gotten pretty decent results. Nickmav1337 • 3 yr. ago rp5 road shoesPhong reflection is an empirical model of local illumination.
