UV Unwrap Node

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 Unwrap 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 Узел Vector Math.

Входы

Выбор

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

Seam

Edges to mark where the mesh is «cut» for the purposes of unwrapping.

Отступ (margin)

The distance to leave between UV islands.

Fill Holes (Заполнить отверстия)

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

Свойства

Method
Angle Based:

This method gives a good 2D representation of a mesh

Conformal:

Uses LSCM (Least Squares Conformal Mapping). This usually gives a less accurate UV mapping than Angle Based, but works better for simpler objects

Вывод (output)

UV

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

Примечание

In order for Blender to recognize the created attribute as a UV map, it must be created with the Нода Store Named Attribute (сохранение названного атрибута) on the Face Corner domain with the 2D Vector data type. This is necessary because there is no 2D Vector socket type.
