I´m having this problem in Maya 2009:
I set to render an animation of 500 frames, from a perspective view, from 1 to 440 frame.
The render reaches only ´till frame 389. Re render 3 or 4 times, changing from PNGs to JPGs and the result was the same.
Reset the render menu to render from 390 to 440 frame, and in this case, no render is done at all.
Resolution 640x480 in Maya software. It contains only polygons, with no effects at all.
Got 2Gb of memory, a dual core chip and plenty of room on my HD.
Thanx in advance for any clue or solution.
