Batch render works smoothly for all frames except 1

[how-cg]

Hi! Am posting here for the first time.

I have a problem with batch rendering in maya 2009 (64).

I have set up a batch render of 200 frames, with maya's mental ray plugin. It is a simple scene with some props and a slight movement of the camera. The batch render shows that each frame takes around 1 minute to render on the average, however, at frame 147, rendering got stuck at 0%, and remained so for more than 2 hours, until i canceled the mayabatch.

I have tried to just render a single frame for frame 147 using the same settings, waited for over 2 hours, and the blur due to final gather points was not cleared up although the picture somehow showed.

I tried to continue the batch render from frame 148 onwards and the render went smoothly until the last frame averaging at around 1  minute per frame.

Therefore I have come to the conclusion that somehow, something happened at frame 147 resulting in me unable to render it.

Anybody has any clues regarding this? Would appreciate the help.

I specialize in fixing stuff like this. If you send me the scene I can have a look. michiel@thnkr.com

Thank you for offering to help, I think I have worked around it.

The reason that the frame is lagging so much is most likely due to the motion blur applied to a random object floating across the screen, once I turned off the motion blur, the renderwent smoothly.

The curious thing is, previously, how the following frames rendered just as quickly if the object still had motion blur applied to it.

Dow big on screen movement did it have at that frame?

I am attempting to batch render in maya 2009 64 bit.  I can do a playblast without problem, however when I batch render it renders one frame in about a minute and then hangs for about an hour and crashes.  I can batch render simple scenes, so i know its a problem with my file, just no idea what it is.  Is there a way to figgure this out or a script to wrk like batch render I can run?

You should not hijack a thread with a separate problem
