Nodo Empacar islas UV

The Pack UV Islands node rearranges UV islands so they efficiently fill a given UV space. It scales, translates, and optionally rotates islands while keeping a defined margin between them. This is useful for procedurally optimizing UV layouts inside Geometry Nodes workflows, such as generating texture atlases or preparing geometry for baking.

Truco

Unlike the UV Editor operator, this node works non-destructively and can be driven by procedural inputs, making it suitable for automated or parametric UV generation.

Entradas

UV

The UV map to pack. The topology of UV islands is determined from this input.

Selección

Faces to consider when packing islands. Only UV islands that include at least one selected face are affected. UVs belonging exclusively to unselected faces remain unchanged.

Margen

The distance to leave between UV islands, expressed in UV space units.

Rotar

Allow rotating islands to achieve a more efficient packing result.

Método

Determines how the shape of each island is evaluated during packing.

Volumen delimitador:

Uses the axis-aligned bounding box of each island. This is the fastest method but may be less space-efficient.

Envolvente convexa:

Uses the convex hull of each island. This method will not place islands inside holes and provides a balance between accuracy and performance.

Forma exacta:

Uses the full island shape, including concave regions and holes. This produces the tightest packing but is the slowest option.

Inferior izquierda

The bottom-left corner of the region into which islands are packed.

Superior derecha

The top-right corner of the region into which islands are packed.

Salida

UV

The packed UVs, with islands repositioned and scaled according to the node settings.
