Imagine a low-poly sci-fi crate. You have 50 polygons. If you use a Phong tag, the corners will look rounded (bad for hard surface). If you break the Phong tag, the lighting will look faceted. Using Vertex Normal Tool 1.0.5, you can "harden" the normals on the edges of the crate while keeping the large flat faces perfectly smooth. The result: A low-poly asset that looks like it has millions of polygons when standing next to a dynamic light.
: It enables "Average Weighted Normals," which averages vertex normals toward larger faces. This creates smooth, professional bevel-like shading on low-poly models without adding real geometry. Manual Manipulation Vertex Normal Tool 1.0.5 for Cinema 4D
For the solo artist, it unlocks a new level of polish. It is the difference between a model that looks "good" and one that looks "triple-A." Imagine a low-poly sci-fi crate
