Rotation – Обертання¶

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 Viewport Display – Показ Оглядвікна panel.
- Вісь Орієнтації – Orientation Axis
Aligns the X axis of new particles to:
- None – Нема
Глобальна вісь X.
- Normal – Нормаль
The emitter’s surface normal.
- Нормаль-Тангенс – 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.
- Глобально – Global X, Y, Z
Одна з глобальних осей.
- Об’єкт – Object X, Y, Z
One of the emitter’s local axes.
- Randomize – Рандомізація
How much to randomize the particle’s initial rotation (along all axes).
- Phase – Фаза
Initial rotation around the particle’s X axis, going from -1 (-180°) to 1 (180°).
- Рандомізувати Фазу – Randomize Phase
Maximum random rotation to add to the Phase, going from 0 (0°) to 2 (360°).
- Динамічно – Dynamic
Whether the particles“ rotation can change over time.
Кутова Скорість – Angular Velocity¶
Reference – Довідка
- Panel – Панель:
«Система Частинок > Обертання > Кутова Скорість» –
Lets you configure if and how particles should spin over time. Dynamic needs to be enabled for this to work.
- Axis – Вісь
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.
- None – Нема
Spinning is disabled.
- Скорість – Velocity
Spin around the particle’s velocity vector.
- Horizontal – Горизонтально
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 – Вертикально
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.
- Глобально – Global X, Y, Z
Spin around the chosen global axis.
- Random – Випадково
Spin around a random axis.
Підказка
If you use a Провідна Крива – 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 Follow Path Constraint – Примус «Слідування Шляхом» or the legacy Follow option of the curve itself, but these don’t work for particles.)
- Amount – Величина
How fast to spin around the Axis.
