I'm trying to model a book with a leather cover in bryce (thank you, Cardinal, for your blessing).  I've created a terrain to use as the book cover.  I want gold leaf lettering on the terrain/cover.  Is there not some way to boolean in the letters?  I'm thinking I saw that done with numbrs on pool balls before but I can't recall how it is done.

The pic is the terrain.  Texture is 3d and not a mat.

If anyone is interested the terrain is generated from a 2d pic from a paint program.  I simply added a "leather" texture filter to a plane grey image.  Wah lah.
