Are there any changes to rendering in Maya 2010?
Maya 2010 uses the latest mental ray® 3.7.5x renderer core library and includes five additional mental ray for Maya Batch rendering nodes. Each Maya seat now enables artists to use other networked computers to render their sequences faster. The Backburner network render queue manager is intended to be included to help those with smaller rendering pipelines manage the process; larger facilities are expected to be able to integrate the additional mental ray for Maya nodes with their existing render management software.
