I'm trying to make a terrain with rocks scattered about. I made the terrain, imported some rocks I bought from Content Paradise in wavefront.obj format, and use the surface replicator to distribute them. When I render them in an animation using vector motion blur, it looks like motion blur is applied between the instances and the base object (see picture). Have any of you seen this before? Is it something I'm doing wrong or is it a bug? I'm on a Mac Dual 2Ghz PowerPC GR, OS X 10.3.9, 1.5 GB DDR SDRAM. I've updated Carrara to 5.0.4. I'd appreciate any help. Thanks!
