She's a P5 Judy who's face has been modified through the Face Room to characterise the face (so she's basically not Judy anymore). With or without shadows, they're still there. With or without backfacing polygons, they're still there. Took a really close look at her head to see if the teeth were in any strange position. Don't think that's it. This character has rendered fine in the past. Hopefully it's a one off that will never plague me again. Still there has to be a reason for it. For the moment, she can turn her head 90 degrees so those unsightly extra nostrils are out of sight and ought of mind. I appreciate everyone's help to try and overcome this. If someone reads this and knows the answer, please post it. Thanks again all. Chloe
