Note: When the the Transparent preset is selected the SketchUp material Opacity will have no effect. Use the material color to control  the transparency

Thin_Glass – refracts light through a single face as if it were a sheet of glass

Thick_Glass – refracts light through a single face as if going into a block of glass. If it passes through another Thick_Glass face it will refract again as if it is coming out of the glass

Thick_Frosted_Glass - refracts and scatters light through a single face as if it was a rough sheet of glass.  If it passes through another Thick_Frosted_Glass face it will refract and scatter again as if it is coming out of the glass.

Liquid – refracts light in and out of faces in a similar way to Thick_Glass, but the light is bent less. This simulates liquids which have a lower "refractive index" than glass

Diamond – refracts light in and out of faces in a similar way to Thick_Glass, but the light is bent more. This simulates materials like diamonds which have a higher "refractive index" than glass. The higher refractive index also means that more light is reflected off the surface of the material as well as being refracted through it

Glowing_Frosted_Glass0 - Similar to Thick_Frosted_Glass but with a low self illuminating value

Glowing_Frosted_Glass 1 - Similar to Thick_Frosted_Glass but with a medium self illuminating value

Glowing_Frosted_Glass 2 - Similar to Thick_Frosted_Glass but with a high self illuminating value

Glowing_Frosted_Glass 3 - Similar to Thick_Frosted_Glass but with the highest self illuminating value
