Weights

Trọng lượng Sơn Vẽ Công Cụ.

Blender provides a set of helper tools for Weight Painting.

Tùy Chọn Tập Hợp Con (The Subset Option)

Some of the tools also provide a Subset filter to restrict their functionality to only specific vertex groups (in the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel, displayed after the tool is called) with following options:

• Nhóm đang hoạt động (Active Group)

• Xương Tư Thế đã Chọn

• Xương Tư Thế Biến Dạng

• Toàn Bộ các Nhóm (All Groups)

All tools also work with Vertex Selection Masking and Face Selection Masking. In these modes the tools operate only on selected vertices or faces.

Chỉ Định Từ Bao Bì Xương (Assign from Bone Envelopes)

Apply the envelope weight of the selected bone(s) to the selected vertex group.

Chỉ Định tự động Từ các Xương (Assign Automatic from Bone)

Apply from the selected bone(s) to the vertex group the same "auto-weighting" methods as available in the Parent armature menu.

Bình Thường Hóa Tất Cả (Normalize All)

For each vertex, this tool makes sure that the sum of the weights across all vertex groups is equal to 1. This tool normalizes all of the vertex groups, except for locked groups, which keep their weight values untouched.

Khóa cái Đang Hoạt Động (Lock Active)

Giữ các giá trị của nhóm đang hoạt động trong khi bình thường hóa tất cả những cái khác.

Bình Thường Hóa (Normalize)

This tool only works on the active vertex group. All vertices keep their relative weights, but the entire set of weights is scaled up such that the highest weight value is 1.0.

Ví dụ về bình thường hóa.

Phản Chiếu Đối Xứng (Mirror)

The Mirror Vertex Group tool mirrors the weights from one side of a perfectly symmetrical mesh to the opposite side. Only mirroring along local X axis is supported. Those vertices that have no corresponding vertex on the other side will not be affected. But note, the weights are not transferred to the corresponding opposite bone weight group.

Ví dụ về đẩy trồi đối xứng.

Phản Chiếu Trọng Lượng (Mirror Weights)

With this option checked, every selected vertex receives the weight information of its symmetrical counterpart. If both vertices are selected, it will be a weight information exchange; if only one is selected, information from the unselected will overwrite the selected one. Information on weight is passed for the active group only, unless All Groups is checked, in which case it is passed for all groups.

Đảo Bên Tên của Nhóm (Flip Group Names)

Works with selected vertices that belong to vertex groups with "symmetrical names" (with components like "L", "R", "right", "left"). All selected vertices that belong to the active group, or to the symmetrical of the active group, will have their assignation to that group replaced by an assignation to the symmetrical one; however, its weight will be preserved. If All Groups is checked, all assignations to these kind of groups will be replaced by the symmetrical counterpart, also keeping the old weights.

Toàn Bộ các Nhóm (All Groups)

Operate on all vertex groups, instead of the active one.

Phản Chiếu Đối Xứng Cấu Trúc Liên Kết (Topology Mirror)

Mirror for meshes which are not fully symmetric (approximate mirror). See here for more information.

Mẹo

Phóng Chiếu Đối Diện

If you want to create a mirrored weight group for the opposite bone (of a symmetric character), then you can do this:

1. Delete the target vertex group (where the mirrored weights will be placed).

2. Create a copy of the source bone vertex group (the group containing the weights which you want to copy).

3. Rename the new vertex group to the name of the target vertex group (the group you deleted above).

4. Select the target vertex group and call the Mirror tool (use only the Mirror weights option and optionally Topology Mirror if your mesh is not symmetric).

Đảo Nghịch (Invert)

Replaces each Weight of the selected weight group by × -1.0 weight.

Ví dụ:

• Nguyên bản 1.0 chuyển đổi thành 0.0

• Nguyên bản 0.5 giữ nguyên là 0.5

• Nguyên bản 0.0 chuyển đổi thành 1.0

Đảo Nghịch.

Tập Hợp Con (Subset)

Restrict the tool to a subset. See above The Subset Option about how subsets are defined.

Cộng thêm Trọng Lượng (Add Weights)

Add vertices that have no weight before inverting (these weights will all be set to 1.0).

Xóa Trọng Lượng (Remove Weights)

Remove vertices from the vertex group if they are 0.0 after inverting.

Ghi chú

Locked vertex groups are not affected.

Dọn Dẹp (Clean)

Clean Vertex Group Weights unassigns vertices from Vertex Groups whose weights are below the Limit. Removes weights below a given threshold. This tool is useful for clearing your weight groups of very low (or zero) weights.

In the example shown, a cutoff value of 0.2 is used (see operator options below) so all blue parts are cleaned out.

Note, the images use the Show Zero weights Active option so that unreferenced Weights are shown in Black.

Ví dụ về quá trình xóa.

Tập Hợp Con (Subset)

Restrict the tool to a subset. See above The Subset Option for how subsets are defined.

Giới Hạn (Limit)

This is the minimum weight value that will be kept in the group. Weights below this value will be removed from the group.

Giữ Đơn Thể (Keep Single)

Ensure that the Clean tool will not create completely unreferenced vertices (vertices which are not assigned to any vertex group), so each vertex will keep at least one weight, even if it is below the limit value!

Lượng Tử Hóa (Quantize)

This operator uses a process known as Quantization which takes the input weights and clamps each weight to a number of steps between (0 - 1), so there is no longer a smooth gradient between values.

Quantize example (Steps = 2).

Số Bước (Steps)

The number of steps between 0 and 1 to quantize the weights into. For example 5 would allow the following weights [0.0, 0.2, 0.4, 0.6, 0.8, 1.0].

Mức Độ/Số Tầng (Levels)

Adds an offset and a scale to all weights of the selected weight groups. with this tool you can raise or lower the overall "heat" of the weight group.

Ghi chú

No weight will ever be set to values above 1.0 or below 0.0 regardless of the settings.

Ví dụ về quá trình xóa.

Tập Hợp Con (Subset)

Restrict the tool to a subset. See above The Subset Option for how subsets are defined.

Dịch Chuyển (Offset)

A value from the range (-1.0 - 1.0) to be added to all weights in the vertex group.

Gia Lượng (Gain)

All weights in the Subset are multiplied with the gain.

Ghi chú

Whichever Gain and Offset you choose, in all cases the final value of each weight will be clamped to the range (0.0 - 1.0). So you will never get negative weights or overheated areas (weight > 1.0) with this tool.

Mịn Màng (Smooth)

Mẹo

The Smooth tool only works when "Vertex selection masking for painting" is enabled. Otherwise the tool button is grayed out.

Blends the weights of selected vertices with adjacent unselected vertices. This tool only works in vertex select mode.

To understand what the tool really does, let us take a look at a simple example. The selected vertex is connected to four adjacent vertices (marked with a gray circle in the image). All adjacent vertices are unselected. Now the tool calculates the average weight of all connected and unselected vertices. In the example this is:

\((1 + 0 + 0 + 0) / 4 = 0.25\)

This value is multiplied by the factor given in the Operator options (see below).

• If the factor is 0.0 then actually nothing happens at all and the vertex just keeps its value.

• If the factor is 1.0 then the calculated average weight is taken (0.25 here).

• Dragging the factor from 0 to 1 gradually changes from the old value to the calculated average.

Now let us see what happens when we select all but one of the neighbors of the selected vertex as well. Again all connected and unselected vertices are marked with a gray circle. When we call the Smooth tool now and set the Factor to 1.0, then we see different results for each of the selected vertices:

• The top-most and bottom-most selected vertices:

  are surrounded by three unselected vertices, with an average weight of \((1 + 0 + 0) / 3 = 0.333\) So their color has changed to light green.

• The middle vertex:

  is connected to one unselected vertex with weight = 1. So the average weight is 1.0 in this case, thus the selected vertex has changed to red.

• The right vertex:

  is surrounded by three unselected vertices with average weight = \((0 + 0 + 0) / 3 = 0.0\) So the average weight is 0, thus the selected vertex has not changed at all (it was already blue before Smooth was applied).

Finally let us look at a practical example. The middle edge loop has been selected and it will be used for blending the left side to the right side of the area.

• All selected vertices have two unselected adjacent vertices.

• The average weight of the unselected vertices is \((1 + 0) / 2 = 0.5\)

• Thus when the Factor is set to 1.0 then the edge loop turns to green and finally does blend the cold side (right) to the hot side (left).

Hệ Số (Factor)

The effective amount of blending. When Factor is set to 0.0 then the Smooth tool does not do anything. For Factor > 0 the weights of the affected vertices gradually shift from their original value towards the average weight of all connected and unselected vertices (see examples above).

Số Lần Lặp Lại (Iterations)

Number of times to repeat the smoothing operation.

Nới Ra/Co Vào (Expand/Contract)

Positive values expand the selection to neighboring vertices while contract limits to the selection.

Nguồn (Source)

The vertices to mix with.

Toàn Bộ (All)

Smoothing will smooth both selected and deselected vertices.

Duy cái Được Chọn (Only Selected)

Smoothing will only smooth with selected vertices.

Duy cái Chưa Chọn (Only Deselected)

Smoothing will only smooth with deselected vertices.

Thuyên Chuyển Trọng Lượng (Transfer Weights)

Copy weights from other objects to the vertex groups of the active object.

By default this tool copies only the active (selected) vertex group of the source object to the active vertex group of target object or creates a new one if the group does not exist. However, you can change the tool's behavior in the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel.

For example, to transfer all existing vertex groups from the source objects to the target, change the Source Layers Selection option to By Name.

Ghi chú

This tool uses the generic "data transfer", but transfers from all selected objects to active one. Please refer to the Data Transfer docs for options details and explanations.

Chuẩn Bị Quá Trình Sao Chép (Prepare the Copy)

You first select all source objects, and finally the target object (the target object must be the active object).

It is important that the source objects and the target object are at the same location. If they are placed side-by-side, then the weight transfer will not work. (See the Vertex Mapping option.) You can place the objects on different layers, but you have to ensure that all objects are visible when you call the tool.

Now ensure that the target object is in Weight Paint Mode. Open the Toolbar and call the Transfer Weights tool in the Weight Tools panel.

Điều Chỉnh Sự Bối Rối đối với Bảng Thao Tác Sau Cùng (Adjust Last Operation Panel Confusion)

You may notice that the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel stays available after the weight transfer is done. The panel only disappears when you call another Operator that has its own Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel. This can lead to confusion when you use Transfer weights repeatedly after you changed your vertex groups. If you then use the still-visible Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel, then Blender will reset your work to its state right before you initially called the Transfer Weights tool.

So when you want to call the Transfer Weights tool again after you made some changes to your vertex groups, then always use the Transfer Weights button, even if the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel is still available. Unless you really want to reset your changes to the initial call of the tool.

Tổng Giới Hạn (Limit Total)

Reduce the number of weight groups per vertex to the specified Limit. The tool removes lowest weights first until the limit is reached.

Gợi ý

The tool can only work reasonably when more than one weight group is selected.

Tập Hợp Con (Subset)

Restrict the tool to a subset. See above The Subset Option for how subsets are defined.

Giới Hạn (Limit)

Chỉnh Sửa các Biến Dạng (Fix Deforms)

The Fix deforms tool is used to modify an object's nonzero weights so its deformed vertices are at a new defined distance. This is helpful to fix deformations because when complex models are deformed to their extreme poses, they are often visibly bumpy, jagged, or otherwise incorrectly deformed. Using this tool, you can smooth over the deformation.

To use the tool, select the vertices that you would like to move, either in Edit Mode or by using the vertex selection/mask. The operator can now be used and altered with these options:

Khoảng Cách (Distance)

Khoảng cách để di chuyển đến.

Độ Đậm/Sức Mạnh/Cường Độ (Strength)

The distance moved can be changed by this factor.

Độ Chính Xác (Accuracy)

Changes the amount weights are altered with each iteration: lower values are slower.

Ghi chú

Note that if it does not change, then there are no nonzero bone weights that are changed to make it closer to the intended distance.
