oh, silly me, i misunderstood you and kept checking for families,
i switched to the solid attribute, and though it didnt work on the current project, i tried reacreating it in a new file, and it seems to work.
i've uploaded the new example - http://dl.dropbox.com/u/45834687/wallgun.cap
btw what is the practical difference between attributes and families?
anyways, thanks tulamide, always so helpful!
