Weights

Weight Paint Tools.

Blender provides a set of helper tools for Weight Painting.

The Subset Option

Some of the tools also provide a Subset filter to restrict their functionality to only specific vertex groups (in the Adjust Last Operation(最後の操作を調整) panel, displayed after the tool is called) with following options:

• アクティブなグループ

• Selected Pose Bones

• Deform Pose Bones

• 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.

Assign from Bone Envelopes

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

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.

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.

Lock Active

Keep the values of the active group while normalizing all the others.

Normalize(正規化)

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.

Normalize example.

Mirror(ミラー)

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.

Mirror example.

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.

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.

All Groups

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

Topology Mirror(トポロジーによるミラー反転)

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

ちなみに

Mirror to Opposite Bone

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).

Invert(反転)

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

例:

• Original 1.0 converts to 0.0

• Original 0.5 remains 0.5

• Original 0.0 converts to 1.0

Invert.

Subset(使用部分)

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

Add Weights

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

Remove Weights

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

注釈

Locked vertex groups are not affected.

Clean

Clean Vertex Group Weights(頂点グループウェイトを掃除) は、ウェイトが Limit(制限) を下回る 頂点グループ から頂点の割り当てを解除します。指定したしきい値を下回る重みを削除します。このツールは、非常に低い(またはゼロの)ウェイトのウェイトグループをクリーンするのに役立ちます。

ここで示す例では、カットオフ値に0.2を使用しており、(以下のオペレーターオプションを参照)、すべての青い部分がクリーンアップされます。

参照されていないウェイトが黒で表示されるように、画像は Show Zero weights オプションを使用していることに注意してください。

ツールをサブセットに制限します。サブセットの定義方法については、 The Subset Option を参照してください。

Limit(制限)

これは、グループに保持される最小のウェイト値です。この値を下回るウェイトはグループから削除されます。

Keep Single(１つだけ残す)

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!

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).

Steps(ステップ)

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].

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.

注釈

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

Levels example.

Subset(使用部分)

ツールをサブセットに制限します。サブセットの定義方法については、 The Subset Option を参照してください。

Offset(オフセット)

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

Gain(ゲイン)

All weights in the Subset are multiplied with the gain.

注釈

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.

Smooth(スムーズ)

ちなみに

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 color 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 color 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).

Factor(係数)

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).

Iterations(反復)

Number of times to repeat the smoothing operation.

Expand/Contract

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

Source(ソース)

The vertices to mix with.

All(全て)

Smoothing will smooth both selected and deselected vertices.

Only Selected

Smoothing will only smooth with selected vertices.

Only Deselected

Smoothing will only smooth with deselected vertices.

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 Adjust Last Operation(最後の操作を調整) 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.

注釈

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.

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.

Adjust Last Operation Panel Confusion

You may notice that the Adjust Last Operation(最後の操作を調整) panel stays available after the weight transfer is done. The panel only disappears when you call another Operator that has its own Adjust Last Operation(最後の操作を調整) 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 Adjust Last Operation(最後の操作を調整) 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 Adjust Last Operation(最後の操作を調整) panel is still available. Unless you really want to reset your changes to the initial call of the tool.

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:

Distance(距離)

The distance to move to.

Strength(強さ)

The distance moved can be changed by this factor.

Accuracy(精度)

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

注釈

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.
