Thanks, I tried your suggestion, but there's nothing wrong with the parenting. It is related to parenting, but that's not where the problem lies. It works fine with *deformation* motion blur with the exact same center of rotation, so that proves that the problem is in how *transformation *motion blur is being evaluated. When evaluated per point with a global vector, everything's fine. I wish I could force MR to do that even though I'm not actually deforming anything.
