Hi folks. I have an object that has (slightly too) perfectly aligned geometry, but even though the faces of some its parts are perfectly aligned with other faces, the fresnel effect is totally dominant on some suraces, but apparently absent on on other faces with identical orientation. I take it I've done something wrong, but I have no idea what that might be.
As you can see in my test render (cycles) the reflection totally dominates the side and doors, but is not dominant on the small faces just above and below the faces where the reflections are dominant.
It is a single object comprised of smaller meshes that each have a single-user instance of the material, where each instance has various rotations applied to the material instance's texture co-ordinates, however the fresnel in each instance remains identical. Perhaps the most obvious inconsistency is between the faces of the doors and the faces of the plank of wood that make the base of the bookshelf.
This is my first attempt at making a model I want to keep and use elsewhere, so any advice about why this is happening and how to avoid it it in the future would be greatly appreciated.
