I'm not sure what you're looking for, but all FX for all media can be applied to text, either as part of the text, or as a masked part of text.
Can you provide some specifics of what you're looking to accomplish?
i have download 2 examples with my vegas 6 package(name of "additional video fx") but these 2 are not enough to learn...So i need any other text examples...
You really need to spend more time at the VASST site. They have a HUGE number of VEG files that show all sorts of creative way to create amazing text effects with Vegas.
