I'm having trouble rendering my animation i Maya 4. I have a few very simple frames, but they only render part of the image, then an exception occurs and the rendering aborts. I believe this started happening after I added some fur to my character. Does anyone here know if this is a known bug in Maya 4, and if there is some work around?
