Quote - Also, I have been playing around with using Edge Blend to control the scale of the scatter node. I found that certain areas were showing red brightness (like when lighting behind the ear) that shouldnt be. I found setting a high scale, and using an edge blend node to lower the scale as the polys turn to face the camera would help, and it did!  You cant really see the difference in the above image unfortunately

 

Could you share your material room setup for this? I've been looking at that too, but with no real success. Can you post a screen grab?

 

Thanks
