Another perplexing issue. I hope the solution is easy. I have a distinct band that renders across the chest of a character I am working on. It does not appear with just the diffuse map. Only when SSS is in play. I have checked all the materials very closely and not a single one of them has a hint of this band. I have sent the SSS node alone to the material output and it displays this odd band. None of my other nodes are causing this. I also superimposed the mesh over the render to see if anything matched up, and it does not. Furthermore, while I primarily work with self-compiled GIT Blender, I also tested in stable and even 2.73a with identical results.
Of course, this character will have a shirt so this is not a screaming disaster, However it is troubling - the flaw could pop up somewhere else that cannot be so easily hidden so I’d like to find the cause of it if that’s possible. Have any of you seen anything like this?
