When this check box is clear, items with transparency of more than 50% are treated as completely transparent,
and are not rendered.
Use Texture Anti-Aliasing Indicates whether antialiasing is used for procedural textures. Selecting this check
box improves quality, but takes longer to render.
A procedural texture is a mathematically- generated image that represents natural elements such as wood, marble,
granite, metal, stone, and so on. In Presenter, procedural textures have ball-style preview icons.
Hardware Shading Selects the hardware-accelerated shading.
NOTE This option can only be used on machines with OpenGL 1.5 compliant graphics cards.
Choose from the following options:
■ Off - turns off hardware-accelerated shading.
■ Lighting - only lights are shown.
■ Passive Shadows - both lights and shadows are turned off during navigation, and automatically reappear
when navigation stops.
■ Interactive Shadows - both lights and shadows are shown during navigation.

enable Hardware Shading first.
NOTE This option can only be used on machines with OpenGL 1.5 compliant graphics cards.

Choose from the following options:
■ User - the message file only contains user messages (that is, messages generated by message actions in scripts).

internally by Scripter). Debugging enables you to see what is going on in more complex scripts.

Autodesk Navisworks attempts to create one for you.
NOTE You can't use variables in the file path.
