I opened a file from the 2.44 days and when I try to render it blender immediately crashes. Is there some issue with multires in 2.45. And if so, has anyone found a work-around? Thanks.
Please post the .BLEND file that crashed. For best results put it in the Blender bug tracker at http://projects.blender.org/tracker/?atid=125&group_id=9&func=browse.
