Luca, Even if you delete your nodes, their Ops are likely to be kept around in memory so they can be restored by an Undo operation.
Not sure if this will help your case, but you could disable the creation of a new Undo set, then create your nodes, delete them, and re-enable Undos. ex: nuke.Undo().disable() for n in range(10000): a = nuke.nodes.Grade() a['selected'].setValue(True) nukescripts.node_delete(popupOnError=True) nuke.Undo().enable() On Tue, Sep 25, 2012 at 1:40 PM, Luca Fiorentini <luca.fiorent...@gmail.com>wrote: > Hi Howard, > Thanks but this gives me the same result. > If I run this > > [CODE] for n in range(10000): > > a = nuke.nodes.Grade() > > a['selected'].setValue(True) > > nukescripts.node_delete(popupOnError=True) > [/CODE] > > i get 500 megs added for each execution!
