Special Features
The "Angel Ring" (or "Tenshi no Wa") is a stylized highlight often seen on anime hair.
Outline
UTS2 uses the **Inverted Hull** method for outlines, where a second pass renders the mesh inside-out and slightly larger than the original.
Shading Grade Map
The **Shading Grade Map** (SGM) is an advanced workflow that replaces the two separate "Position Maps" with a single grayscale texture. This allows for more organic and complex shadow shapes.
Double Shade with Feather
This is the standard shading mode of UTS2. It simulates the anime production workflow where colors are defined as "Base", "1st Shadow", and "2nd Shadow".
