I'm not sure that it can be done, strictly speaking. By a void box, I suppose you mean an unassigned box register (i.e. \voidb@x); now that I think of it, it is strange that \unhbox\voidb@x is allowed in the first place (if nothing is assigned to the register, how can you unhbox it?). On the Lua side, an unassigned box register (e.g. tex.box["voidb@x"]) returns nil (unlike an unassigned count register, which returns 0), so I'd say the Lua equivalent of a void box is nil. Of course, if you're just looking for an empty box, that's easy (except you have to specify if it's an horizontal or vertical box): node.new(node.id"hlist", 2) or node.new(node.id"vlist", 2) (the second argument is optional but later it might be useful to know that this is a handmade box). Best, Paul
