The bottles are now visualized using the Hardware Shading.
Choosing a Shading Model
The bottles are using the Default shader, which has the Blinn shading model.
There are four types of shading model in Alias:
■ LAMBERT is useful for representing matte surfaces like plaster walls,
paper, or blackboards.
■ PHONG is more complex, and gives highlights suitable for high-gloss
plastic, glass, and metals.
■ BLINN provides more flexible highlights that can be adjusted for softer
plastics, satin finishes, and natural materials.
■ LIGHTSOURCE makes the object look like it emits light, like an
incandescent bulb or flame.
As you gain more experience with shaders, you will understand which Shading
Models will produce the results you want.
