Brush Panel.

La peinture nécessite des pinceaux at Blender fournit un panneau Brush dans le Tool Shelf quand il opère en Weight Paint Mode.

Brush

Dans le menu Data-Block vous trouverez des préréglages de pinceau prédéfinis. Et vous pouvez créer vos propres préréglages personnalisés au besoin.

Weight W

Le poids (couleur) à utiliser par le pinceau. Cependant, la valeur de poids est appliqué au groupe de sommets de différentes manières selon le mode Brush Blending sélectionné (voir ci-dessous).

Use Ctrl-LMB to sample the weight value of clicked vertex. Shift-LMB lets you select the group from which to sample from.

Strength

C’est la quantité de peinture à appliquer par coup de pinceau. Ce que cela signifie exactement dépend aussi du mode Brush Blending.

Radius

Le rayon définit la zone d’influence du pinceau.

Blend mode

Le Blending mode du pinceau definit de quelle manière la valeur de poids est appliquée au groupe de sommets pendant la peinture.

Mix
In this Blending mode the Weight value defines the target weight that will eventually be reached when you paint long enough on the same location of the mesh. And the strength determines how many strokes you need to arrive at the target weight. Note that for strength = 1.0 the target weight is painted immediately, and for Weight = 0.0 the brush just does nothing.
Add
In this Blending mode the specified weight value is added to the vertex weights. The strength determines which fraction of the weight gets added per stroke. However, the brush will not paint weight values above 1.0.
Subtract
In this Blending mode the specified weight value is subtracted from the vertex weights. The strength determines which fraction of the weight gets removed per stroke. However, the brush will not paint weight values below 0.0.
Lighten
In this Blending mode the specified weight value is interpreted as the target weight. Very similar to the Mix Blending mode, but only weights below the target weight are affected. Weights above the target weight remain unchanged.
Darken
This Blending mode is very similar to the Lighten Blending mode. But only weights above the target weight are affected. Weights below the target weight remain unchanged.
Multiply

Multiplie les poids des sommets avec la valeur de poids spécifiée. C’est en quelque sorte une substraction, mais la quantité de poids supprimée est maintenant dépendante de la valeur de poids elle-même.

Blur

Lisse le poids des sommets adjacents. Dans ce mode la valeur de poids est ignorée. La force définit le niveau de lissage appliqué.

Accumulate

This option keeps applying smoothing on top of the previous result.

Indice

  • Disable when painting individual vertices on lower poly modules.
  • Enable for more dense geometry, or when you want to increase the blur effect.
Auto Normalize

Ensures that all deforming vertex groups add up to one while painting. When this option is turned off, then all weights of a vertex can have any value between 0.0 and 1.0. However, when Vertex Groups are used as Deform Groups for character animation then Blender always interprets the weight values relative to each other. That is, Blender always does a normalization over all deform bones. Hence in practice it is not necessary to maintain a strict normalization and further normalizing weights should not affect animation at all.

This option works most intuitively when used to maintain normalization while painting on top of weights that are already normalized with some other tool.

Multi-Paint

Peint simultanément sur tous les groupes de sommets, d’une manière qui préserve leur influence relative. Ceci peut être utile dans l’ajustement des poids dans une zone qui est affectée par plus de trois bones à la fois, ex. certaines zones du visage d’un personnage.

This option is only useful in the Armature tab, where you can select multiple Vertex Groups by selecting multiple Pose bones. Once at least two Vertex Groups are selected, viewport colors and paint logic switch to Multi-Paint Mode, using the sum of the selected groups’ weights if Auto Normalize is enabled, and the average otherwise. Any paint operations aimed at this collective weight are applied to individual Vertex Group weights in such way that their ratio stays the same.

Since the ratio is undefined if all weights are zero, Multi-Paint cannot operate on vertices that do not have any weight assigned to the relevant Vertex Groups. For this reason it also does not allow reducing the weight all the way to zero. When used with X-Mirror, it only guarantees completely a symmetrical result if weights are initially symmetrical.

Astuce

While Multi-Paint cannot directly paint on zero-weight vertices, it is possible to use the Smooth Weight tool to copy a reasonable non-zero weight distribution from adjacent vertices without leaving Multi-Paint Mode or changing bone selection.

Pour ce faire, activez la sélection de sommet, sélectionnez les sommets cibles, et appliquez une itération de l’outil utilisant les groupes de sommets de Selected Pose Bones avec un facteur bas. Après cela, peignez simplement dessus pour fixer le poids collectif désiré.
