Vertex Weights(頂点ウェイト) パネル。

A vertex group assigns a weight (a number between 0 and 1) to each vertex it contains. A group can have multiple vertices, and each vertex can be part of multiple groups.

The Vertex Weights panel in the 3D Viewport's Sidebar shows the vertex groups for the active vertex, and lets you see and edit the associated weights. It's available in Edit Mode, as well as in Weight Paint Mode when Vertex Selection is enabled in the header.

頂点グループカテゴリ

While all vertex groups are technically the same, we can still divide them into two types depending on how they're used:

変形グループ

Also sometimes called "weight group" or "weight map," this type of vertex group determines which vertices are affected by a certain bone in the Armature. In other words, it defines which part of the mesh deforms when the bone moves around.

他のグループ

The remaining vertex groups are used with shape keys, modifiers, and other areas.

The deform vertex groups are related to each other: the deformation weights of every vertex typically need to add up to 1. For this reason, you can use the filter buttons at the top of the panel to show only these vertex groups (or to exclude them).

ウェイトテーブル

The Weight Table shows all the weights associated with the active vertex, which is the vertex that was selected last (and is highlighted in white). If there is no active vertex, or it isn't part of any vertex group, the panel is not displayed.

アクティブグループを設定

You can click the name of a vertex group to make it the active one.

Edit Mode(編集モード)でのウェイト表示

Edit Mode(編集モード)でウェイト表示を有効にする。

When you are in Edit Mode, you can make the weights of the active group visible on the mesh: open the Mesh Edit Mode Overlays popover and enable the Vertex Group Weights option.

ウェイトの変更

You can change the weight for a vertex group by either clicking the number and typing a new one or by dragging left and right with LMB. You can also click the arrows (only shown when hovering) to change the weight in steps of 0.01.

Copy a Weight

The Paste Weight to Selected button copies the weight from the active vertex to the other selected vertices. Note that, even though it uses the word "paste," it doesn't interact with the Copy button and in fact doesn't use the clipboard at all.

Delete a Weight

The Delete Weight button removes the active vertex from the vertex group, making the row disappear from the list.

オペレーター

Vertex weight operators.

Normalize(正規化)

Recalculates the weights of the active vertex so that they add up to 1.0 while retaining their relative magnitude.

Copy(コピー)

Copies all the weights from the active vertex to the other selected vertices.

Tip

Both tools only work on the vertex groups that match the current filter setting.

固定

Locked vertex group.

If a vertex group is locked, its weights become uneditable, and the buttons for copying and normalizing weights become disabled.

Tip

The Normalize and Copy buttons only become disabled if there's a locked vertex group in the current list. If (for example) only non-deforming vertex groups are locked, you can switch to the Deform filter and normalize the groups that way.
