yes precedurals are what i want, my bad for not mentioning =P

personally i hate texture maps for any case, aside from greyscale control maps for impossible-to-create patterns

thanks for the setup, i'll play around it. again the colors don't matter to me since i can easily switch them to what i wish - another reason i prefer to avoid texture maps - and what i've been working on mainly is trying to achieve a good dark greenish, or mixed with white veins, mainly a good looking pattern, the "marble effects" such as sss and shininess can go on anything (:
