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:

该方法提供了不错的网格的二维表达。

共形:

使用LSCM (Least Squared Conformal Mapping)。UV映射效果通常没有基于角度准确，不过对于简单物体效果更好。

输出

UV

在选定的面孔中，每个面孔角落的生成的UV坐标在0和1之间。

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.
