well, unless all your objects use the same material anyway, you'll
probably have to add the ClipPlaneChunk to all objects materials you
want clipped (hint: in OSGAction.h there are functions called traverse
which will call a functor for each node in a subtree, they could be
usefull). If everything uses the same material anyway a MaterialGroup
could help you as well.
Hope it helps,
Carsten
