Warning: If the selection arrow is the specified option for the preview object, and no object is selected, you will get a warning that a preview cannot be generated. This will also happen if the selection arrow is the default and you open the Material editor with no object selected.

Pattern

...

Note: TurboCAD has several defined patterns, but if you want to apply your own image as a pattern, see Creating a New Material.

...

To see the entire list of available patterns, open the drop-down menu. Each type of pattern has its own set of unique parameters.

Reflectance

This category defines a material's luster: its brightness, polish, dullness, etc. For example, a brick's reflectance is "Matte" - it is flat and does not reflect light.

...

Some stone materials have "Mirror" reflectance to simulate shininess.

Transparency

This category is relevant for transparent glass and plastic materials. For example, "Eroded" transparency simulates a bumpy or uneven glass surface.

...

 

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.

Texture

This category enables you to make a surface appear rough or bumpy. The rendering engine simulates shadows along the surface to create the textured effect. For example, you can define a Leather texture.

"Ice" is defined with a rough texture.

Wrapping

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.
