A number of 3d text presets are included in Action, such as rotating or fading text to add to your scene. These presets can help you add complex text effects with just a few clicks.
The 3D Text Preset file browser appears, pointing to the default location of the presets: usr/discreet/<product home>/3d_text_presets.
The 3d text preset is then appended to your Action scene. In the 3D Text menu, you can change the default text string of the preset.
For a listing and description of all available 3d text presets, see the 3D Text Presets Reference Guide, available at http://www.autodesk.com/smoke-documentation-2011.
