Well i was thinking cracked dirt looks real nice on the track edge, i know the new dillo too can make cracked texs but i only want it in specific places. Ive tried stained glass plugin but it didnt look so good :-\
heres an example wat id like the cracked dirt to look(in middle below table top) like this if possible ;)

but here's my way
in photoshop
filter/render/clouds (black and white)
filter/pixelate/crystalize
filter/texture/stained glass
then get the paint bucket, set mode to 'clear' and click on a black part.
then ctrl+click on that layer
inverse selection (ctrl+shift+i)
new layer, paint bucket on normal, fill in the selection.
you should be able to take it from there.
btw: you could jsut download a cracked rock texture
