Hi

Find the 'Tower' tutorial which comes with the maya docs

An cheap way to make stuff tile on -anything- but without much regard to scale is just to apply Unitize-UV's, and that's that. Some people do their UV stuff by hand. I like to just select bunches of faces and do planar mappings onto them, and use the manipulator tool to adjust the position, scaling and rotation. You can planar map rocks onto a wall, for example, then grab the manipulator tool and drag around the blue corners in the 4 edges of the tool and this will scale the texture up/down/squish/stretch it etc. You can also grab multiple objects and do planar mappings on them both at the same time, and the placements via manipulators will mesh up, it's neato.
