hi,
i have many objs,and need unhide parameters for them,such as “xform motionsamples”.and don't want do it one by one.
so i need do it in python, may be node.addspareparmtuple works,but alittle hard to do it.
is there any other command or can you show me a full code about node.addspareparmtuple.

Do you mean rendering properties? If so, the Hscript command “opproperty” lets you use wildcards (*) to add them to many nodes at once. The UI is super painful for this

yes!
that's nice
thank you pbowmar
