If you have an Onyx you can use detail textures, which are are large texture
map of low resolution and a high resolution texture map of small size which is
stippled all over the larger map. This works well for the application you are
decribing. To read about detail textures you can do a man on texdef look for
TX_DETAIL. Also do a man on pfTexture looking for pfTexDetail.
