Hotkey: F9
Description
The EdgeSplit modifier splits edges within a mesh. The edges to split can be determined from the edge angle or edges marked as sharp can be split.
Splitting an edge affects vertex normal generation at that edge, making the edge appear sharp. 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. 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.
Options
- 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 Specials → Mark Sharp menu item, accessible by (Ctrl E) in editmode.
