So what does it mean to say that a material is physically based? Well essentially, it means that you don't have to jump through hoops in order to get accurate reflectivity on your material. For example, in older 3D packages, and indeed in previous versions of modo, things such as fresnel reflections had to set up manually. So first of all, what are fresnel reflections? Fresnel reflections are the phenomena of reflections becoming stronger as the surface moves perpendicular to the eye of the camera. So what this means is, at a glancing angle, the surface becomes more reflective, as you can see here on the roof of the train, or indeed with these bright reflections at the top of the chimneys. And in the real world, all surfaces have these fresnel reflections…
