UV Unwrap Node

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

Faces to participate in the unwrap operation. UVs that are part of any other face will not be affected.

缝合边

Edges to mark where the mesh is “cut” for the purposes of unwrapping.

边距

The distance to leave between UV islands.

填充洞面

Virtually fill holes in mesh before unwrapping, to better avoid overlaps and preserve symmetry.

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

The generated UV coordinates between 0 and 1 for each face corner in the selected faces.
