Maybe a stupid idea, but how about parsing the maya ascii file to detect connections and save a list to disk, then go through that list when deleting?
Also, putting flushUndo in the loop will help a lot, so that maya wont have to keep 200 000 deletes in memory. Even save as for every 1000 iterations, in case Maya dies in the middle of the process (I once had to get rid of 150 000 keyframes the animator had made on every single vertice in a scene, so I feel your pain) On Tue, Dec 8, 2009 at 5:59 PM, Sune <[email protected]> wrote: > Uh, I can see that "delete" also takes forever, so please take this > into account as well > > On Dec 8, 3:16 pm, Sune <[email protected]> wrote: > > Hi, > > > > I need to look at a bunch of nodes and check if they have more than > > one connections.
