- Physical materials govern colisions: rebound, friction, etc.
- Visual (?) materials govern the interaction with light (that's a very correct way of putting it). They call this Materials. I'll discuss.
Material (visual) properties:
- Albedo - In reality the definition of albedo is the percentage of light it reflects, whiteness - blackness, but here they use it for the color when there is no light (strange...maybe they mean under neutral, white light). Albedo comes from latin albus = white. We can assign one value to the whole oblect or a map.
- Metalic (map and slider) - the way it reflects light,
- Roughness - more on the way it reflects light, see diffuse and specular to know more, later on.
- And there are more maps which can be stored in the chanels of the rgb+alpha images
WHat I don't know yet is how the maps are atributed to the geometry!
