Модификатор Разделение Рёбер(EdgeSplit)

Mode: Any Mode

Panel: Editing Context → Modifiers

Hotkey: F9


Модификатор Разделения Рёбер разделяет рёбра в объекте. Рёбра на разделение могут быть определенны от угла между ними или рёбер помеченных как острые допустимые для разделения.

Разделение ребёр влияет на генерирование нормалей вершин (для освещения) на данном ребре, заставляя казаться его острым. Hence, this modifier can be used to achieve the same effect as the Autosmooth button, making edges appear sharp when their angle is above a certain threshold. It can also be used for manual control of the smoothing process, where the user defines which edges should appear smooth or sharp (see Mesh Smoothing for other ways to do this). If desired, both modes can be active at once. The output of the EdgeSplit modifier is available to export scripts, making it quite useful for creators of game content.


EdgeSplit modifier
From Edge Angle
If this button is enabled, edges will be split if their edge angle is greater than the Split Angle setting.
  • The edge angle is the angle between the two faces which use that edge.
  • If more than two faces use an edge, it is always split.
  • If fewer than two faces use an edge, it is never split.
Split Angle
This is the angle above which edges will be split if the From Edge Angle button is selected, from 0° (all edges are split) to 180° (no edges are split).
From Marked As Sharp
If this button is enabled, edges will be split if they are marked as sharp, using the Edge SpecialsMark Sharp menu item, accessible by (CtrlE) in editmode.
