Children(子)¶
参照
- Panel(パネル)
Children are Hair or Emitter particles originating from individual particles. 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. The number and visualization of the children can be changed without a recalculation of the physics.
If you activate children, the parents are no longer rendered. This can be enabled in the Render panel Parent Particles. By default, parent particles are not rendered because the shape of the children can be quite different from that of their parents.
共通のオプション¶
- Child Type
- None(なし)
No children are generated.
- Simple(シンプル)
Children are emitted from the parent position.
- Interpolated(補間)
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 Viewport.
- Render Amount
The number of children to be rendered.
- Length(長さ)
Length of child paths.
- Threshold(しきい値)
Amount of particles left untouched by child path length.
- Seed(シード)
Offset in the random number table for child particles, to get a different randomized result.
Clumping¶
参照
- Panel(パネル)
- Use Clump Curve
Use カーブウィジェット instead of parameters.
- Clump
Clumping amount along child strands. The children may meet at their tip (1.0) or start together at their root (-1.0).
- Shape(シェイプ)
Form of Clump. Either inverse parabolic (0.99) or exponentially (-0.99).
- Twist(ツイスト)
(未稿)。
- Use Twist Curve
(未稿)。
Roughness¶
参照
- Panel(パネル)
- Use Roughness Curve
Use カーブウィジェット 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¶
参照
- Panel(パネル)
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
- Nothing(なし)
Deactivated.
- Curl
Children grow in a spiral around the parent hairs.
- Radial(放射)
Children form around the parent a wave shape that passes through the parent hair.
- Wave
Children form a wave, all in the same direction.
- Braid
Children braid themselves around the parent hair.
- Spiral
Generates a spiral at the end of each hair.
- Radius, Resolution
Define the overall size.
- Shape(シェイプ)
Makes a the spiral grow in- or outward.
注釈
Alignment Limitations
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(振幅)
The amplitude of the offset.
- Clump
How much clump effects kink amplitude.
- Flatness
How flat the hairs are.
- Frequency(頻度)
The frequency of the offset (1/total length). The higher the frequency the more rotations are done.
- Shape(シェイプ)
Where the rotation starts (offset of rotation).
Simple(シンプル)¶
- Size(サイズ)
A multiplier for children size.
- Random Size
Random variation to the size of child particles.
- Radius(半径)
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.
- Roundness
The roundness of the children around their parents. Either in a sphere (1.0) or in-plane (0.0).
