Modificador Forrar

The Skin modifier uses vertices and edges to create a skinned surface, using a per-vertex radius to better define the shape. The output is mostly quads, although some triangles will appear around intersections.

It is a quick way to generate base meshes for sculpting and/or smooth organic shapes with arbitrary topology.

Nota

Faces in the original geometry are ignored.

El modificador Forrar.

Suavizado de ramificaciones

A branch point is a vertex with three or more connected edges. These areas tend to produce more complicated topology, some of which may overlap. This setting relaxes the surface around these points, with the side effect of shrinking it.

Simetría

These checkboxes are used to keep the output topology symmetrical in their respective axes. In other words, using it avoids merging triangles across an axis unless the triangles form a symmetric quad.

Nota

They do not add geometry flipped across an axis. For that, the Mirror modifier should be used, typically placed above the Skin one.

Sombreado suave

Producirá caras con un sombreado suave, en vez de facetado. El sombreado suave/facetado de la geometría original no será preservado.

Crear esqueleto

Create an armature on top of the object. Each edge becomes a bone.

Nota

If the root vertex has more than one adjacent edge, an extra bone will be created to serve as the root.

This tool does the following:

  1. A new armature object is added with bones matching the input mesh. The active selection is switched to the new armature.

  2. Weight groups are added to the input mesh. The Skin modifier propagates these weights to the output as well.

  3. An Armature modifier is added directly below the Skin one. Note that the Armature modifier is being applied after the Skin one because it should only deform the output, whereas if it were above, it might change the resulting topology.

Agregar datos de forro

This modifier uses a custom set of data in the mesh, that is generated automatically when you add the modifier the first time.

However, you may remove that data, or loose it some way or the other. That operator will generate it again.

Marcar / Eliminar como sueltos

By default, a branch vertex (vertex with three or more connected edges) will generate extra edge loops along adjacent edges in order to keep the output tight. Branches can be made loose by clicking Mark Loose, which will allow the output to stretch between all adjacent vertices. This can be disabled again by clicking Clear Loose.

Marcar como raíz

Marking a vertex as root causes that vertex to be used for calculating rotations for connected limbs. Root vertices also affect the armature output, they will be used as the origin for the root bones.

Each set of connected vertices should have one root node (one is selected by default if you do not assign any manually). Mark Root enforces the one-root per set rule, so it is not necessary to manually unmark roots.

Igualar radios

Hará que el radio del forro de los vértices seleccionados sea igual en cada eje.

Datos de forro de la malla

That modifier needs a set of specific data in the original mesh to work properly. This data allows you to define the root vertices of each tree, which ones are loose, and the size (radius) of the skin at each vertex. The radii of input vertices can be individually scaled in Edit Mode with the Redimensionar forro.
