UV 展开#
The UV Unwrap Node generates a UV map islands based on a selection of seam edges. The node implicitly performs a Pack Islands operation upon completion, because the results may not be generally useful otherwise.

The 展开 operator performs a similar operation in the UV editor. Unlike the Unwrap operator, the node doesn't perform aspect ratio correction, because it is trivial to implement with a 矢量运算节点.
输入#
- 选择
参与解包操作的面。属于任何其他面的UV将不会受到影响。
- 缝合边
边缘,用于标记网格被 "切割" 的地方,以达到解包的目的。
- 边距
UV孤岛之间的间距。
- 填充洞面
在解包前虚拟填充网格中的孔,以更好地避免重叠和保持对称性。
属性#
- 方法
- 基于角度:
This method gives a good 2D representation of a mesh
- 共形:
Uses LSCM (Least Squares Conformal Mapping). This usually gives a less accurate UV mapping than Angle Based, but works better for simpler objects
输出#
- UV
为所选面的每个面拐角生成介于 0 和 1 之间的 UV 坐标。
Note
In order for Blender to recognize the created attribute as a UV map, it must be created with the 存储已命名属性 on the Face Corner domain with the 2D Vector data type. This is necessary because there is no 2D Vector socket type.
