I’ve noticed a weird effect on some of my meshes. See the attached pictures below. Here’s the scene set up, both objects are mesh cylinders that I’ve “set smooth.” The light is a spot (only one in this scene, although I’ve detected this in many of my projects). The cylinders have a simple material (all defaults except the color).
The weird effect I don’t understand is that dark banding you see on the left-hand cylinder. I’ve learned how to get rid of it by toggling the “Auto Smooth” button in the Mesh editing panel. This is what I did to the right-hand cylinder. But now there is no noticable specular highlight on the object. (Same material!). (However, simply setting specularity to 0 in material does not negate the weird effect). I tried re-calculating the normals…no effect.
Can anyone offer some insight into this weird effect—what is it? How to better counter it (w/o losing specular)?
In advance, thank-you, I do.
