Thin_Dull – refracts light through a face as if it were a thin sheet of very slightly reflective material

Thin_Shiny – refracts light through a face as if it were a thin sheet of smooth material with some reflectivity on the surface

Thin_Reflective – refracts light through a face as if it were a thin sheet of polished material, so you will see strong reflections off the surface as well as seeing though it

Thick_Dull – refracts light as if going into a solid material. It will only refract again (coming out of the material) if it passes through another translucent or transparent face

Thick_Shiny – refracts light as if going into a solid smooth material with some reflectivity on the surface.  It will only refract again (coming out of the material) if it passes through another translucent or transparent face

Thick_Reflective – refracts light as if going into a solid polished material, so you will see strong reflections off the surface as well as seeing though it.  It will only refract again (coming out of the material) if it passes through another translucent or transparent face

Liquid_Dull – similar to the Thick_Dull finish, but it uses a slightly lower "refractive index", so the light bends less than Thick as it's refracted through the material

Liquid_Shiny – similar to the Thick_Shiny finish, but it uses a slightly lower "refractive index", so the light bends less than Thick as it's refracted through the material

Liquid_Reflective – similar to the Thick_Reflective finish, but it uses a slightly lower "refractive index", so the light bends less than Thick as it's refracted through the material
