Вращение (rotation)#
Ссылка
- Панель:
These parameters specify how the individual particles are rotated at the start of, and during, their lifetime. You can visualize their orientation by setting Display As to Axis in the Отображение во вьюпорте (viewport display) panel.
- Ось ориентации (orientation axis)
Выравнивает ось X новых частиц по:
- Нет (none)
Глобальная ось X.
- Нормаль (normal)
The emitter’s surface normal.
- Нормаль-касательная (normal-tangent)
The emitter’s surface normal, additionally aligning the particle’s Y axis to the positive V direction in the emitter’s active UV map. This makes it possible to deform the emitter while keeping particle rotation consistent.
- Velocity / Hair
The particle’s initial velocity vector/hair growth direction.
- Глобальная X, Y, Z (global)
Одна из глобальных осей.
- Объектная X, Y, Z (object)
One of the emitter’s local axes.
- Рандомизировать (randomize)
How much to randomize the particle’s initial rotation (along all axes).
- Фаза (phase)
Initial rotation around the particle’s X axis, going from -1 (-180°) to 1 (180°).
- Рандомизировать фазу (randomize phase)
Maximum random rotation to add to the Phase, going from 0 (0°) to 2 (360°).
- С динамикой (dynamic)
Whether the particles“ rotation can change over time.
Угловая скорость (angular velocity)#
Ссылка
- Панель:
Lets you configure if and how particles should spin over time. Dynamic needs to be enabled for this to work.
- Ось (axis)
The axis to spin around. If this is set to Velocity, Horizontal, or Vertical, particles will additionally spin to keep the same orientation relative to their direction of movement, even if Amount is zero.
- Нет (none)
Spinning is disabled.
- Cкорость (velocity)
Spin around the particle’s velocity vector.
- Horizontal
Spin around the axis that’s horizontal (lying in the global XY plane) and perpendicular to the particle’s velocity. Particles moving along the global Z axis won’t spin because no unique rotation axis exists in this case.
- Vertical
Spin around the axis that’s perpendicular to both the particle’s velocity and the above Horizontal axis. Particles moving along the global Z axis won’t spin.
- Глобальная X, Y, Z (global)
Spin around the chosen global axis.
- Случайно (random)
Spin around a random axis.
Подсказка
If you use a Направляющая по кривой (curve guide) and want the particles to always point in the direction of the curve, you should set the Orientation Axis to Velocity / Hair, enable Dynamic, and set the Angular Velocity Axis to Velocity.
(For a regular object, you’d normally use the Follow Curve option of a Ограничение «Следовать по пути» (Follow Path Constraint) or the legacy Follow option of the curve itself, but these don’t work for particles.)
- Величина (amount)
How fast to spin around the Axis.
