In terms of vertex normals, how can you specify that the tip of a cone be sharp, while making the body of the cone smooth? The shading in the example below is undesirable, because the vertex normals of the cone tips are collapsed into one orientation: pointing straight up.
Thinking it out, I’d guess you’d want the vertex normals at the tip to be arranged in a kind of flattened fan layout, where adjacent faces’ vertex normals are collapsed into one, but the vertex normals don’t all collapse into one big super-normal pointing up. I know there are a handful of custom vertex normal tools available for Blender, but what’s the best way to automate this particular configuration? Thanks!
