This category is relevant for transparent glass and plastic materials. For example, "Eroded" transparency simulates a bumpy or uneven glass surface.
Not all glass or plastic materials have Transparency defined. For example, "Tinted Glass" is smooth, and its transparency is actually defined as part of the "Glass" reflectance.
This is a good example of how complex, and powerful, the TurboCAD materials engine is. You can get similar results by defining parameters in different categories.

This category defines how a pattern or image wraps around surfaces of a 3D object.For materials, such as Granite, the wrapping is defined as "None," which pastes the pattern without distortion onto faces along the three major planes.
The "UV" wrapping is similar to "None" except that you can specify how the pattern is scaled. With "Auto Axis" the pattern is oriented according to the WCS, regardless of where the faces of the 3D object are located and oriented. You can also specify the axis along which the pattern will be projected.
