Here's another tip.. You notice how in your original tif, the letters are crisp and in the bryce render they come out fuzzy, it's because you don't have the same resolution on your tiff as your end product.. What that means is, do the texture tiff at 72 dpi and you'll get crisp letters at 72 dpi render... If you do 300 dpi texture and 72 dpi render, you get fuzzy letters... :)
