Macha Posted June 7, 2011 Share Posted June 7, 2011 (edited) I've just rendered out a loong sequence of frames on a small render farm and I noticed that -bizarrely- one machine (the fastest) has written out picnc instead of pic... So, every 4th frame or so is the wrong format. I have no idea why it did that because it's always worked in the past. Is there a way to re-render only those bad frames? I used deadline if that helps.

lukeiamyourfather Posted June 7, 2011 Share Posted June 7, 2011 Sounds like the license configuration on the one machine got messed up. Maybe during install of a newer version of Houdini? I think Deadline can take arbitrary frame ranges so if you can get a list of the bad frames then Deadline should be able to render just those. A script could find the bad frames if there are a lot of them. Python has a handy method in the os module, os.listdir() if I remember correctly. Then split those up with built in string method endswith(). http://docs.python.org/library/os.html http://docs.python.org/library/stdtypes.html Quote Link to comment Share on other sites More sharing options...
Macha Posted June 7, 2011 Author Share Posted June 7, 2011 Yes, it was a licensing error on a single machine. Restarting didn't solve it, it needed a bit more extra care. Quote Link to comment Share on other sites More sharing options...
edward Posted June 7, 2011 Share Posted June 7, 2011 So, every 4th frame or so is the wrong format.\ .... Is there a way to re-render only those bad frames? Can't you just set the Step to 4 in the frame range? Quote Link to comment Share on other sites More sharing options...
Macha Posted June 7, 2011 Author Share Posted June 7, 2011 Can't you just set the Step to 4 in the frame range? It's about 4 frames. Sometimes 2, sometimes none, sometimes 6. One machine rendered one frame so the time taken for each image differs slightly. I just rerendered all the ones done by the one machine. Deadline allows me to select frames rendered by machine.

kubabuk Posted June 8, 2011 Share Posted June 8, 2011 You can filter the ncpic frames by walking down the folder and compare extensions. Next just pass the bad frames to mantra or render queue again. Quote Link to comment Share on other sites More sharing options...
Adam Ferestad Posted June 8, 2011 Share Posted June 8, 2011 Wow, I actually found a solution for you Marc, yay. Frame Dependency ROP. Set it to "List of Frames" under "Frame Depends on" and then just put your frame numbers in down below. Quote Link to comment Share on other sites More sharing options...
