Crianças¶

Children are Hair and Keyed particles assigned subparticles. They make it possible to work primarily with a relatively low amount of Parent particles, for whom the physics are calculated. The children are then aligned to their parents. Without recalculating the physics the number and visualization of the children can be changed.
Children can be emitted from particles or from faces (with some different options). Emission from Faces has some advantages, especially the distribution is more even on each face (which makes it better suitable for fur and the like). However, children from particles follow their parents better, e.g. if you have a soft body animation and do not want the hair to penetrate the emitting mesh. But see also our manual page about Hair.
If you turn on children the parents are no longer rendered (which makes sense because the shape of the children may be quite different from that of their parents). If you want to see the parents additionally turn on the Parents button in the Visualization panel.
Children carry the same material as their parents and are colored according to the exact place from where they are emitted (so all children may have different color or other attributes).
The possible options depend from the type of particle system, and if you work with Children from faces or Children from particles. We do not show every possible combination, only the settings for a Hair particle system.
Opções comuns¶
- Tipo de criança
- Nenhum
- No children are generated.
- Simples
- Children are emitted from the parent position.
- Interpoladas
- Children are emitted between the Parent particles on the faces of a mesh. They interpolate between adjacent parents. This is especially useful for fur, because you can achieve an even distribution. Some of the children can become virtual parents, which are influencing other particles nearby.
- Display Amount
- The number of children in the 3D View.
- Render Amount
- The number of children to be rendered.
- Comprimento
- Comprimento dos caminhos das crianças.
- Ajuste
- Quantidade de partículas que são deixadas sem toque pelo comprimento do caminho de crianças.
- Semente
- Deslocamento dentro de uma tabela de números aleatórios para as partículas crianças, para obter um resultado diferentemente aleatorizado.
Clumping¶
Referência
| Panel: |
|---|
- Usar curvas para formar feixes
- Use Assistente de curvas instead of parameters.
- Agrupamento
- Clumping amount along child strands. The children may meet at their tip (1.0) or start together at their root (-1.0).
- Formato
- Form of Clump. Either inverse parabolic (0.99) or exponentially (-0.99).
- Twist
- Todo.
- Use Twist Curve
- Todo.
Rugosidade¶
Referência
| Panel: |
|---|
- Usar curva de rugosidade
- Use Assistente de curvas instead of parameters.
- Uniform, Size
- It is based on children location so it varies the paths in a similar way when the children are near.
- Endpoint, Shape
- «Rough End» randomizes path ends (a bit like random negative clumping). Shape may be varied from <1 (parabolic) to 10.0 (hyperbolic).
- Random, Size, Threshold
- It is based on a random vector so it is not the same for nearby children. The threshold can be specified to apply this to only a part of children. This is useful for creating a few stray children that will not do what others do.
Kink¶

Child particles with Kink.
With Kink you can rotate the children around the parent. See Fig. Child particles with Kink. above picture for the different types of Kink.
- Kink Type
- Nenhum
- Desativado.
- Encaracolar
- Children grow in a spiral around the parent hairs.
- Radial
- Children form around the parent a wave shape that passes through the parent hair.
- Ondas
- Children form a wave, all in the same direction.
- Trançar
- Children braid themselves around the parent hair.
- Espiral
Generates a spiral at the end of each hair.
- Raio, Resolução
- Define the overall size.
- Formato
- Makes a the spiral grow in- or outward.
Nota
Limitações de alinhamento
When hair is pointing straight up (along the chosen spiral axis, default Z), spirals may not show up! This is a limitation of the projection method used. Giving a slight tilt or random orientation to hairs fixes this.
- Amplitude
- A amplitude do deslocamento.
- Agrupamento
- Define quanto o agrupamento afeta a amplitude de torção.
- Nivelamento
- Define quão lisos os cabelos são.
- Frequência
- The frequency of the offset (1/total length). The higher the frequency the more rotations are done.
- Formato
- Where the rotation starts (offset of rotation).
Simples¶
- Tamanho
- Only for Emitter. A multiplier for children size.
- Random Size
- Variação aleatória para o tamanho das partículas crianças.
- Radius
- The radius in which the children are distributed around their parents. This is 3D, so children may be emitted higher or lower than their parents.
- Circularidade
- The roundness of the children around their parents. Either in a sphere (1.0) or in-plane (0.0).
Interpoladas¶
- Virtual Parents
- Quantidade de parentes virtuais relacionados.
- Cabelos longos
- Calcula as crianças que vestem bem os cabelos longos.
