default, the Basic profile is used.
4. Select the Smoothed Textures check box if you want textures to look smooth but take longer to
render. Clear it if you want textures to appear pixelated but render faster.
5. Select the Filtered Textures check box if you want to turn on mipmapping. This will improve the
appearance of textures in the distance.
6. Clear the Interactive Materials check box if you want to turn off texture display during navigation.
The materials reappear automatically when navigation ceases, as long as the Full Render rendering
style is on. Clearing this check box will ease the load on less capable graphics cards and give less
drop out in heavily textured scenes.
7. Clear the Interactive Lighting check box if you want to turn off Presenter lights during navigation.
The lights reappear automatically when navigation ceases, as long as the Full Lights lighting style is
on. Clearing this option will ease the load on less capable graphics cards and give less drop out in
heavily lit scenes.
8. Use the Max Texture Size drop-down list to set the maximum size that any texture can be (in pixels,
e.g. 128 is 128 pixels x 128 pixels). The higher the value, the more MB in memory will be taken and
thus performance could be affected on less capable graphics cards.
9. Use the Max Image Texture Size drop-down list to set the maximum size that any texture image can
be (in pixels, e.g. 256 is 256 pixels x 256 pixels). The higher the value, the more MB in memory will
be taken and thus performance could be affected on less capable graphics cards.
10. Similarly, use the Max Background Texture drop-down list to set the maximum size that the
background texture can be (in pixels, e.g. 256 is 256 pixels x 256 pixels). The higher the value, the
more MB in memory will be taken and thus performance could be affected on less capable graphics
cards.
11. Select the Blend Transparent Textures check box if you want better quality but slower rendering of
transparent items in the main navigation window. With this option off, items with transparency of
more than 50% are treated as completely transparent and not rendered at all.
12. Select the Use Texture Anti-Aliasing check box if you want procedural materials (such as some
bricks and tiles - you can tell a procedural material in Presenter because it has a ball style preview
icon) to be rendered using anti-aliasing. With this option on, it will take longer to open files containing
procedural textures, but the quality will be better.
13. Hardware Shading can only be utilized on machines with OpenGL 1.5 compliant graphics cards.
From the Hardware Shading drop-down list, select:
• Interactive Shadows. Select this option to enable lights and shadows whilst navigating.
• Passive Shadows. Select this option to disable lights and shadows whilst navigating, then turn
them on when navigation ceases.
• Lighting. Select this option to turn lighting on with no shadows.
• Off. Select this option to have no hardware shading enabled.
14. Select Hardware Bump Maps check box to display bump map textures interactively, whilst
navigating. This can only be utilized on a machine with an OpenGL 1.5 compliant graphics card.
Hardware Shading also needs to be enabled.
