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.

• Off. Select this option to have no hardware shading enabled.

navigating. This can only be utilized on a machine with an OpenGL 1.5 compliant graphics card.
