Render Elements issue

[Streetwise]

I'm having an issue with bad buckets on an object. It's happening to JUST the female silhouette figure and ONLY the lower portion. It affects MultiMatte, ZDepth, WireColor, Reflection,etc. I haven't run DRBucket element yet, but clearly one of my node(s) is wigging out. I just want to know why that particular spot and why the guy isn't affected? Could it have to do with geometry? They are both biped models but from different sources.

Did you check in the VRayDRBucket RE if a specific machine is causing the issue? Not sure why only a portion of the model is getting the issue, a good idea may be to send the scene along with logs from the machines to support@chaosgroup.com so we can take a look.
