model items. You can also use this tab to create new materials, or customize existing materials.
• Lighting - includes a variety of lighting options, which can be selected and applied to the model. You
can also customize lighting options, if you want.
• RPC - Rich Photorealistic Content, RPC, can be added from various sources, including websites.
RPC's include images of people, trees, cars etc.
• Effects- includes a variety of backgrounds and environments, which can be selected and applied to
the model scene. Some existing backgrounds can be customized, or new backgrounds can be
created. You can also add backgrounds and environments from other sources, such as websites.
• Rendering - includes a variety of rendering styles, which can be selected and applied to the model. A
render style affects the way a scene is rendered. You can also use this tab to create new render
styles, or customize existing render styles.
• Texture Space - defines the way in which a texture is applied to a model item, for example, applying a
cylindrical texture space to a pipe will provide a more natural effect.
• Rules - enables materials to be applied to models according to user-define criteria. This can be used,
for example, to speed up the application of materials to groups of items.
The Materials, Lighting, Effects and Rendering tabs are divided into two panes. The left hand pane
contains the archives and the right hand pane contains the scene's palette, which defines what materials,
lighting, effects and render styles are used in the scene. Archives are shown in a tree structure and are
defined in the LightWorks Archive (.lwa) format.
The Rendering Style Toolbar
While Presenter can be used for photorealistic renderings, it can also be used for OpenGL interactive
rendering and once you've set up the scene with Presenter, you can view the materials and lights in
NavisWorks. There are special rendering styles to interactively preview the Presenter materials and lights
called Full Lights and Full Render on the Rendering Style toolbar:

Using the Presenter Archives
There are three pre-defined archives that are installed with Presenter:
• The Recommended archives contain materials, lighting, effects and rendering styles that are
recommended for most users. These include materials, lights and effects that can be seen during
interactive navigation in NavisWorks and can be fully rendered with OpenGL. Of course, they will look
better when rendered photorealistically.
• Additional materials, light studios, effects and render styles are available in the Standard archive.
These include materials that cannot be fully reproduced using OpenGL and therefore will not be seen
properly in interactive mode, or until a full photorealistic render is done.
• Any materials, lights, effects and render styles from any archive can be used as a template starter for
your own definitions, but the Templates archive contains instances of each type of material, light,
