F-Curve Modifiers – Модифікатори Ф-Кривих¶
Посилання
- Panel – Панель:
F-Curve modifiers are similar to object modifiers, in that they add non-destructive effects that can be adjusted at any time and layered to create more complex effects.
Modifiers are evaluated from top to bottom. You can change their order by dragging the dots in their top right corner.
Some modifiers require being first and cannot be used together. These currently include the Cycles and Smooth (Gaussian) modifiers.
Інтерфейс¶
- Назва
By default, modifiers are named after their function, but this can be changed.
- Mute – Приглушення
Click the checkbox in a modifier’s header to disable it.
- Видалення – Delete
Click the cross in a modifier’s header to delete it.
- Influence – Вплив
Lets you blend between the original curve and the modified one.
- Restrict Frame Range – Обмеження Діапазону Кадрів
- Start/End – Старт/Кінець
Кадр, на якому вплив модифікатора починається/закінчується.
- Blend In/Out
The number of frames, relative the start/end values above, it takes the modifier to fade in/out.
Adding a Modifier – Додання Модифікатора¶
Панель Modifiers – «Модифікатори».¶
F-Curve Modifiers can be added in several ways. Via the Channel Menu in the Graph Editor, the channel region context menu (right click in the channel region), plus they can be added and managed in the Modifiers tab of the Sidebar.
To add a modifier, first select an F-Curve (in the channel region or by selecting one of its keyframes), then chose Add F-Curve Modifer from one of the menus or by clicking the Add Modifier dropdown in the Sidebar. This will let you choose which type of the modifier to add to the selected F-Curves.
Deleting F-Curve Modifiers¶
Just like adding an F-Curve Modifier, there are several ways you can remove them. Single modifiers can be removed by clicking the X icon next to the modifier in the Sidebar. Multiple modifiers can be removed at once with the Delete F-Curve Modifiers operator.
This can be found in the Channel Menu, or the Channel Region context menu (right click in the channel region). After chosing this menu option, you can open the redo panel to adjust the settings if needed.
Redo Panel¶
- Режим
Method used to remove F-Curve Modifiers from the selected curves.
- Remove All:
This will delete all the F-Curve Modifiers from the selected curves (default option).
- Remove Type:
Only remove the specific type of modifier from the selected curves, leaving the others untouched.
- Remove First:
Remove the modifier that is at the top stack on each of the selected curves.
- Тип
Specify which type of modifier to remove (this option will only be visible when the Mode is set to „Remove Type“).
Types of Modifiers – Типи Модифікаторів¶
Generator Modifier – Модифікатор «Генератор»¶
Creates a polynomial function. These are basic mathematical formulas that represent lines, parabolas, and other more complex curves, depending on the values used.

xfor this polynomial.- Constant – Константно
The constants A, B, C… in the equation.
Built-in Function Modifier – Модифікатор «Вбудована Функція»¶
Це додаткові формули, кожна з яких має однакові опції для керування формою. Проконсультуйтеся з довідником з математики щодо детальнішої інформації про кожну функцію:
- Тип
The built-in function to use:
Normalized Sine: \(sin(x)/x\)
- Additive – Доповнення
Add the function to the curve rather than replacing it.
- Amplitude – Амплітуда
Наладнує масштабування по Y.
- Phase Multiplier – Фазовий Множник
Наладнує масштабування по X.
- Phase Offset – Фазовий Зсув
Наладнує зсув по X.
- Value Offset – Зсув Значення
Наладнує зсув по Y.
Envelope Modifier – Модифікатор «Оболонк໶
Lets you reshape the curve. First, you define an envelope, which consists of two horizontal lines that more or less match the curve’s lower and upper bounds. Then, you add control points, where each point can push, squeeze, and stretch the envelope (and the curve along with it) at a certain frame.
The Envelope modifier.¶
- Посилання
The value which the envelope is centered around.
- Min/Max
The offset from the reference value to the envelope’s initial lower/upper bound.
- Add Control Point – Додання Керувальної Точки
Adds a control point at the current frame.
- Вказування – Point
- Frame – Кадр
The frame of the control point.
- Min/Max
The offset from the reference value to the envelope’s adjusted lower/upper bound at this frame.
Cycles Modifier – Модифікатор «Цикл軶
Makes the curve repeat itself.
Примітка
The Cycles Modifier has to be the first modifier in the list.
This modifier needs to know exactly where the keyframes are located, which is not possible when other modifiers are processed first. This means this modifier is not compatible with the Smooth (Gaussian) Modifier.
- Before/After Mode – Режим Перед/Після
- No Cycles – Нема Циклів
Do not repeat the curve before/after the original.
- Repeat Motion – Повтор Руху
Repeats the curve, keeping the values of each copy the same.
- Repeat with Offset – Повтор зі Зсувом
Repeats the curve, offsetting each copy vertically so that its first keyframe matches the previous last keyframe.
- Repeat Mirrored – Повтор Дзеркально
Repeats the curve, flipping every other copy horizontally.
- Count – Рахунок
The number of copies to create. A value of 0 means infinite.
Trivially Cyclic Curves – Тривіально Циклічні Криві¶
Коли режим циклу Cycle Mode для обох урешті-решт задано як Repeat Motion – «Повтор Руху» або Repeat with Offset – «Повтор зі Зсувом» і жодні інші опції модифікатора не змінені відносно їх стандарту, визначається простий безконечний цикл.
Цей спеціальний випадок отримує деяку додаткову підтримку для інших областей Blender’а:
Розміщення автоматичного держака Безьє знає про цей цикл та наладнує досягнення плавного переходу.
The Cycle-Aware Keying option can be enabled to take the cycle into account when inserting new keyframes.
Noise Modifier – Модифікатор «Шу컶
Modifies the curve with a noise formula. This is useful for adding subtle or extreme randomness to animated movements, like camera shake.
- Blend Type – Тип Змішання
- Replace – Заміна:
Adds noise in the range [-0.5, 0.5].
- Додати:
Adds noise in the range [0, 1].
- Subtract – Відняття:
Subtracts noise in the range [0, 1].
- Multiply – Множення:
Multiplies by noise in the range [0, 1].
- Масштаб
Changes the horizontal scale of the noise. Higher values make for less dense oscillation.
- Strength – Сила
Changes the vertical scale of the noise.
- Offset – Зсув
Зсуває шум у часі.
- Phase – Фаза
Наладнує базис випадковості шуму.
- Depth – Глибина
Наладнує деталізацію функції шуму.
- Лакунарність – Lacunarity
Gap between successive frequencies. Depth has to be greater than 0 for this to have an effect.
- Шорсткість
The amount of high frequency detail. Depth has to be greater than 0 for this to have an effect.
Limits Modifier – Модифікатор «Ліміт軶
Limits the curve to specific time and value ranges.
- Minimum, Maximum X
Removes the original curve data to the left of the minimum frame and to the right of the maximum, replacing it by Constant extrapolation.
- Minimum, Maximum Y
Clamps the curve values, never letting them go below the minimum or above the maximum.
Stepped Interpolation Modifier – Модифікатор «Покрокова Інтерполяція»¶
Gives the curve a stepped appearance by sampling it every N frames and making it hold its value after each sample. In a sense, this lowers the curve’s frame rate by letting it change its value less frequently, producing choppy movement as a result.
- Step Size – Розмір Кроку
The number of frames to hold each step.
- Offset – Зсув
The number of frames to offset the sample points.
- Початковий Кадр
The frame where to start applying the effect.
- End Frame – Кадр Кінця
The frame where to stop applying the effect.
Smooth (Gaussian) Modifier¶
Uses Gaussian smoothing to reduce detail and noise in the curve. It performs the same smoothing as the Smoothing Operator.
This uses linear interpolation for subframes which can introduce issues related to motion blur.
Note that this can be a resource-heavy modifier, and its effect on performance can become noticeable when used on many F-Curves.
Примітка
The Smooth (Gaussian) modifier has to be the first modifier in the list.
This modifier needs to know exactly where the keyframes are located, which is not possible when other modifiers are processed first. This means this modifier is not compatible with the Cycles Modifier.
- Сигма – Sigma
The shape of the Gaussian distribution in frames. Lower values will increase sharpness, reducing the smoothing effect. Larger values will result in more smoothing, but are limited by the Filter Width (see below).
- Filter Width
The number of frames the filter «sees» around each keyframe. Higher values allow more smoothing (larger Sigma can then smooth over more frames), but this will decrease performance.
