I wasn’t sure where to put this, but I finally decided this is the best spot.
I am not new to blender(since 2.43) or 3d, and I think this is the first time this has happened to me (bad memory)
I have some black faces on my model, I have found out what is causing it, a normal map. When I turn on the normal map I get the black faces (this happens on other models using other normal maps)
“Black faces” in my experience are caused by “normals facing the wrong way.” (As well you know…) Could it possibly be that the map causes the normal-vector for these pixels to “go over the edge?”
What happens to the effect that you are seeing when you increase or decrease the influence of the map? Exactly which channels of data are being modulated by the map, and to in what amounts? What is the range of +/- offset values contained in the map?
If “this happens on other models using other maps …” do you see any sort of common-thread between the various cases? (He said, grasping at straws while worrying that one day he might encounter the same :eek: himself…)
