Question by opdenis · Jan 23, 2017 at 10:40 AM · shaderreflection

Metallic reflections - my fault or Unity bug?

I have set Albedo texture, Normal map texture and set Metallic to 0, but the "ring" on the column still has reflections:

Is it Unity bug with Standart shader or I have made an error?

I could not attach hi-res textures, but without them there is the error too.

To correctly import shaded object, you have to set new import normals setting in Unity: Model -> Normals & Tangents -> Normals -> Calculate Smoothing Angle = 60

DON'T use default import setting!

Hi @opdenis,

You set metallic to 0 but have you messed around with the Smoothness setting? this could be something to look at maybe. alt text

Yes, I have set Smoothness = 0, but there is still a reflection.

How did you create your texture maps? do you have Spec and OCC?

Well, first of all - my "the preview ball" is the same as yours. So I think, "$$anonymous$$etallic" and "Smoothness" are working. Second - if I DO NOT use my textures (Albedo and Normal map) I have the same effect with light reflection. And it is ONLY on "ring" part, other parts od that column are correct. Do you have this problem too, or I just have incorrect light settings or smth else? alt text

This "bug" only exists if I use Smooth in Blender. If I don't use smooth - there is no reflection on "ring" part of the mesh. But why this happens only with "ring" part, but no other ones?

alt text

I think, it is bug of Blender exporter or Unity importer - if I import mesh ".blender"-format, there is no such bug. It only appears when I import Wavefront (.obj) mesh.
