Does this callback solve your "right before render" problem? http://docs.thefoundry.co.uk/nuke/90/pythondevguide/callbacks.html?highlight=beforerender
As for calling something during render, well Nuke provides the executeInMainThread() set of functions, NOTE: these only work in GUI mode: http://docs.thefoundry.co.uk/nuke/90/pythondevguide/threading.html?highlight=executeinmainthread Otherwise, the problem is a standard threading issue, i.e. you could spawn a thread when you receive beforeRender() to do some tertiary work and kill it on afterRender(). However, if you want to communicate with Nuke from a custom thread whilst in render/terminal mode you may experience some problems calling non-thread safe interfaces (e.g. nuke.createNode()), which is something we hope to fix in the not to distant future. Does that answer you question? :) On 26 April 2015 at 04:16, Sam Cole <samb...@gmail.com> wrote: > In the same vein, what's the easiest way to call something during a render > without touching write nodes? e.g. If I want to call a pyscript buttons > execute right before a render but not mess with any of the facility > preflight etc. > > > > On Sat, Apr 25, 2015 at 1:44 AM, Frank Harrison <fr...@thefoundry.co.uk> > wrote: > >> Just saying that you don't want to rely on having a valid nuke module, >> Root_Node, DDImage infrastructure, etc.. >> >> If it's a gui-only thing you could connect a slot to the aboutToQuit() >> signal >> >> http://doc.qt.io/qt-4.8/qcoreapplication.html#aboutToQuit >> >> >> On 24 April 2015 at 14:19, Fredrik Averpil <fredrik.aver...@gmail.com> >> wrote: >> >>> Hi Frank, >>> >>> I just ran a test here with atExit, and that worked fine.
