Arghhhhh! The sheer HORROR of multi-replicate! I take back my previous statement - I have no clue how this function works. By entering random numbers in the multirep parameters box I can get objects to follow a path, but there's no way the bastards will rotate so that they're always at a set angle. Looks like it's back to doing it by hand - the reliable, if slow method... ;) Oh, I think metaballs is just in 5, though I've never used any other version so I'm not sure.
