Modificadores de curvas-f
Reference
- Panel
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. Like object modifiers, F-Curve modifiers are evaluated from the top down. In other words, the top modifier is calculated first and consequent modifiers are calculated in order. Modifiers can be moved by dragging the modifier box from the top right.
Modifiers can be muted or hidden by toggling the checkbox in the modifier’s panel header. They can be removed using the delete button in the modifier’s panel header.
Adicionando um modificador

The F-Curve modifier panel is located in the Sidebar region. Select a curve by selecting one of its curve points, or by selecting the channel list. Click on the Add Modifier menu to select a modifier.
Tipos de modificadores
Generator Modifier
Generator creates a polynomial function. These are basic mathematical formulas that represent lines, parabolas, and other more complex curves, depending on the values used.
- Mode
Method used to represent the equation.
- Expanded Polynomial
Equation in the form \(y = x^1 + x^2 + ... + x^n\).
- Factorized Polynomial
Equation in the form \(y = (Ax + B)(Cx + D)\).
- Aditivo
This option causes the modifier to be added to the curve, instead of replacing it by default.
- Order
Specify the order of the polynomial, or the highest power of
Xfor this polynomial. (Number of coefficients: 1.)Change the Coefficient values to reshape the curve.

- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Built-in Function Modifier
These are additional formulas, each with the same options to control their shape. Consult mathematics reference for more detailed information on each function:
- Tipo
The built-in function to use.
- Aditivo
This option causes the modifier to be added to the curve, instead of replacing it by default.
- Amplitude
Ajusta o escalonamento em Y.
- Multiplicador de fase
Ajusta o escalonamento em X.
- Deslocamento de fase
Ajusta o deslocamento em X.
- Deslocamento de valor
Ajusta o deslocamento em Y.
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Envelope Modifier
Allows you to adjust the overall shape of a curve with control points.
- Reference
Set the Y value the envelope is centered around.
- Mínimo
Distância mais baixa a partir do valor de referência para uma influência padrão de
1:1.- Máximo
Distância mais alta a partir do valor de referência para uma influência padrão de
1:1.- Add Control Point
Add a set of control points. They will be created at the current frame.
- Point
- Quadro
Set the frame number for the control point.
- Mínimo
Specifies the lower control point’s position.
- Máximo
Specifies the upper control point’s position.
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Cycles Modifier
Cycles allows you add cyclic motion to a curve that has two or more control points. The options can be set for before and after the curve.
Nota
The Cycles Modifier can only be the first modifier.
- Before/After Mode
- No Cycles
Do not repeat curve data before/after.
- Repetir movimento
Repeats the curve data, while maintaining their values each cycle.
- Repetir com deslocamento
Repeats the curve data, but offsets the value of the first point to the value of the last point each cycle.
- Repetir espelhando
Each cycle the curve data is flipped across the X axis.
- Contagem
Set the number of times to cycle the data. A value of 0 cycles the data infinitely.
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Trivially Cyclic Curves
When the Cycle Mode for both ends is set to either Repeat Motion or Repeat with Offset, and no other options of the modifier are changed from their defaults, it defines a simple infinite cycle.
This special case receives some additional support from other areas of Blender:
Automatic Bézier handle placement is aware of the cycle and adjusts to achieve a smooth transition.
The Cycle-Aware Keying option can be enabled to take the cycle into account when inserting new keyframes.
Noise Modifier
Modifies the curve with a noise formula. This is useful for creating subtle or extreme randomness to animated movements, like camera shake.
- Tipo de mescla
- Substituir
Adds a -0.5 to 0.5 range noise function to the curve.
- Adicionar
Adds a 0 to 1 range noise function to the curve.
- Subtract
Subtracts a 0 to 1 range noise function to the curve.
- Multiplicar
Multiplies a 0 to 1 range noise function to the curve.
- Scale
Adjust the overall size of the noise. Values further from 0 give less frequent noise.
- Strength
Ajusta o escalonamento da função de ruído em Y.
- Deslocamento
Desloca o ruído ao longo do tempo.
- Fase
Ajusta a semente aleatória do ruído.
- Profundidade
Adjusts how detailed the noise function is.
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Limits Modifier
Limit curve values to specified X and Y ranges.
- Minimum X, Y
Cuts a curve off at these frames ranges, and sets their minimum value at those points.
- Minimum X, Y
Truncates the curve values to a range.
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
Stepped Interpolation Modifier
Gives the curve a stepped appearance by rounding values down within a certain range of frames.
- Tamanho dos passos
Specify the number of frames to hold each frame.
- Deslocamento
Número referencial de quadros antes que os quadros sejam retidos (use para manter padrões de retenção de «1-3» vs «5-7»).
- Start Frame
Restringe o modificador para agir somente antes de seu quadro «final».
- End Frame
Restringe o modificador para agir somente após o seu quadro «inicial».
- Influência
Controls the percentage of affect the modifier has on the F-Curve.
Restrict Frame Range
- Início e final
The frame on which the modifier’s effect starts/ends.
- Blend In, Out
The number of frames, relative the start/end values above, the modifier takes to fade in/out.
