法向¶

可以用来编辑法向的参考 法线编辑修改器。
加权法向修改器 可以通过不同的方法改变法向, 包括 面强度 (参考下文)。
You can also copy normals from another mesh using Data Transfer (operator or modifier).
反转方向¶

This will reverse the normals direction of all selected faces. Note that this allows you to precisely control the direction (not the orientation, which is always perpendicular to the face) of your normals, as only the selected faces are flipped.
重算法线方向¶

Ctrl-N 和 Shift-Ctrl-N
这些工具会重新计算选择面法向让他们指向面的体积侧(区分于内)。体积不需要封闭;内外的区分取决于面的连接角度。

This is an interactive tool. As you move the mouse around, the selected normals are rotated. You can also invoke the Rotate Normals tool by pressing the Rotate transform key R, followed by N.
指向目标体¶

Alt-L
设置所有选择的法向到目标并 Return or LMB 确认。
按键以设置目标:
鼠标游标 M
枢轴 L
原始物体 O
游标(单击设置) Ctrl-LMB
A mesh item selection (set by this click) Ctrl-RMB
- 模式
工具的操作可以修改,如果以下按键已经按下:
- 对齐 A
All normals will point in the same direction: from the center of selected points to the target.
- 球形化 S
Each normal will be an interpolation between its original value and the direction to the target.
- 反转 I
The normal directions are reversed from what was specified above.
- 重置 R
重置自定义法向回操作开始前的状态。
按面强度选择¶

Another way to affect normals is to set a Face Strength on the faces of the model. The Face Strength can be either Weak, Medium, or Strong. The idea is that the 加权法向修改器 can be set to pay attention to the Face Strength as follows: When combining the normals that meet at a vertex, only the faces with the strongest Face Strength will contribute to the final value.
例如,如果3个面链接一个顶点并且有强中弱三个面权重,只有强的面的法相会被取为最终结果。
使用子菜单选择 弱、中,或 强 之一。然后,此工具将选择所选面强度相对应的面。
