Your shader looks ok. You said this started happening after P5. That's a clue, but not a certainty, that it might have something to do with looking at the "wrong" or "back" side of a polygon. P6 and P7 handle them differently than P5 and the issue comes up about once every ten days in this forum, mostly to do with hair. 

Perhaps the item has reversed normals?

Try enabling Normals_Forward on all the materials of the item.

Failing that, disconnect your Sphere_Map on the reflection and render again to see if it has something to do with that. I can't imagine how the simple bump setup or the diffuse color could produce bright RED like that. But if the normals are somehow goofy, this will have a huge impact on the "reflection" lookup via the Sphere_Map.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
