Everything is easy when you know how, knowing how is the hardest part.., I don't use Matrices much, but you can texture individual tiles of a matrix and the best way to learn this is to go through the examples provided in DB/DBPRO and then try changing the examples enough untill you discover what is going on, just tweek small things here and there to see what things do and then progress until you can create and tile you own matrix with your own textures..
