Bộ Điều Chỉnh Da (Skin Modifier)

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.

Ghi chú

Faces in the original geometry are ignored.

Bộ Điều Chỉnh Da.

Làm Mịn Phân Nhánh (Branch Smoothing)

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.

Đối Xứng (Symmetry)

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.

Ghi chú

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

Tô Bóng Mịn Màng (Smooth Shading)

Các bề mặt đầu ra có tô bóng mịn màng, chứ không bằng phẳng. Tô bóng mịn màng/bằng phẳng của hình học ở đầu vào sẽ không được bảo tồn nữa.

Tạo Cốt (Create Armature)

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

Ghi chú

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

Hướng dẫn này bao gồm các chủ đề sau:

  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.

Thêm Dữ Liệu Da (Add Skin Data)

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.

Đánh Dấu/Xóa Dấu Rời Rạc (Mark/Clear Loose)

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.

Đánh Dấu Là Gốc (Mark Root)

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.

Cân Bằng Bán Kính (Equalize Radii)

Makes the skin radii of selected vertices equal on each axis.

Dữ Liệu Khung Lưới của Da (Skin Mesh Data)

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 Đổi Kích Thước của Da (Skin Resize).
