Vertex Weights panel.
Як згадувалось раніше у Групах Вершин (Vertex Groups) кожен запис у Групі Вершин містить також значення ваги у діапазоні від 0.0 до 1.0. Blender надає панель Вагів Вершин (Vertex Weights), з якої ви можете отримати (або редагувати) інформацію про ваги вершин кожної Вершини сітки. Тобто, до якої Групи належить вершина і з якою вагою.
The Vertex Weights panel can be found in the right Sidebar region of the 3D View. It is available in Edit Mode and in Weight Paint Mode (when Vertex Selection masking is enabled as well).
Категорії Груп Вершин (Vertex Group Categories)¶
Насправді, ми не маємо ніяких жорстких категорій для Груп Вершин у Blender. Технічно всі вони поводяться однаково. Проте, ми можемо визначити дві неявні категорії Груп Вершин:
Групи Деформацій (Deform Groups)¶
Ці Групи Вершин інколи називаються Групами Вагів (Weight Groups) або Мапи Вагів (Weight Maps). Вони використовуються для визначення таблиці вагів кісток Арматур (Armature bones). Всі Групи Деформацій Об’єкта жорстко відносяться один до одного через їхні значення ваги.
Strictly speaking, the sum of all deform weights for any vertex of a mesh should be exactly 1.0. In Blender this constraint is a bit relaxed (see below). Nevertheless, Deform Groups should always be seen as related to each other. Hence, we have provided a filter that allows restricting the Vertex Weight panel to display only the Deform bones of an Object.
Інші Групи (Other Groups)¶
All other usages of Vertex Groups are summarized into the Other category. These vertex groups can be found within Shape keys, Modifiers, etc. There is really no good name for this category, so we kept it simple and named it Other.
Таблиця Вагів (Weight Table)¶
The Weight Table shows all weights associated to the active vertex. Note that a vertex does not necessarily have to be associated to any vertex groups. In that case the Vertex Weights Panel is not displayed.
Порада
Активна Вершина
That is the most recently selected vertex. This vertex is always highlighted so that you can see it easily in the mesh. If the active Vertex does not have weights, or there is no active vertex selected at the moment, then the Vertex Weights Panel disappears.
Each row in the Weight table contains four active elements:
Change Active Group.
Set the Active Group¶
As soon as you select any of the Vertex Group Names in the Weight table, the referenced Vertex Group becomes the new Active group.
Enable display of Weights in Edit Mode.
Display Weights in Edit Mode¶
When you are in edit mode, you can make the Weights of the active Group visible on the mesh:
Search the Mesh Display panel in the Sidebar region. And there enable the Show Weights option. Now you can see the weights of the active Vertex Group displayed on the mesh surface.
Weights in Edit Mode.
Edit Weights in Edit Mode¶
It is now very easy to work with Vertex Groups in Edit Mode. All edit options of the mesh are available and you have direct visual control over how your Weights change when you edit the weight values.
Change Weight value.
Change a Weight¶
You can either enter a new weight value manually (click on the number and edit the value), or you can change the weight by LMB and while holding down the mouse button, drag right or left to increase/decrease the weight value. You also can use the right/left arrows displayed around the weight value to change the weight in steps.
Paste weights.
Pasting¶
LMB the Paste Icon allows you to forward a single weight of the active Vertex to all selected vertices. But note that weights are only pasted to vertices which already have a weight value in the affected Vertex Group.
Delete weights.
Deleting¶
LMB the Delete Icon will instantly remove the weight from the active vertex. Thus the entire row disappears when you click on the delete icon.
Tools¶
Vertex Weights panel.
- Normalize
- Normalizes the weights of the active Vertex. That is all weights of the active vertex are recalculated such that their relative weight is maintained and the weight sum is 1.0.
- Copy
- Copies all weights defined for the active Vertex to all selected vertices. Thus all previously defined weights are overwritten.
Порада
The filter setting is respected
Note that both tools only work on the Vertex Groups currently displayed in the Weights Table. So if for example only the Deform weights are displayed, then Normalize and Copy only affect the Deform bones.
Locking¶
Locked Vertex Weights panel.
Whenever a Weight Group is locked, all data changing tools get disabled:
- Normalize the vertex Weights.
- Copy the Vertex weights.
- Change the Weight of the active vertices.
- Paste to selected vertices.
Порада
The filter setting is respected
If you have for example all deform weight groups unlocked and all other vertex groups locked, then you can safely select Deform from the Filter row and use all available tools from the Weight table again.
