UV 展开#

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.
