Modifiers Tab
F-Curve modifiers are similar to Object modifiers. They allow to add adjustable non destructive effects. And they can be layered on top of each other.

F-Curve modifiers are similar to Object modifiers. They allow to add adjustable non destructive effects. And they can be layered on top of each other.
Different to the Object modifiers you can't reorder this modifiers. You have to create it in the order that you need it.

Curve Type
The available wave forms for the curve.
| Entry | What it does |
|---|---|

| Amplitude | The amplitude of the curve wave. Adjusts the Y scaling. |
| Phase Multiplier | A phase multiplier for the curve wave. Adjusts the X scaling. |
| Phase Offset | A phase offset for the curve wave. Adjusts the Y scaling. |
| Value Offset | A constant value offset for the whole curve. Adjusts the X scaling. |
| Use Influence | Temper the F-Curve Modifier effect by a default influence factor. Expanding the Use Influence sets it to active. It reveals a value slider then. · Influence: The influence factor. |
Restrict Frame Range
Expanding the Restrict Frame range sets it to active. It reveals some value slider then.
| Entry | What it does |
|---|---|
| Start / End | The start and end frame of the generated curve. |
| In / Out | Fade the curve in or out for chosen frame numbers. |
Envelope modifier
The Envelope modifier allows you to modify the overall shape of the curve by control points.
| Entry | What it does |
|---|---|
| Envelope | Reference Value: Set the Y value to center the envelope around. · Min: The lower distance from reference value for 1:1 default influence. · Max: The higher distance from reference value for 1:1 default influence. |
| Add Control Point | Add a control point. A control point has two sub points, a lower control point and a higher control point. |
Use Influence
Temper the F-Curve Modifier effect by a default influence factor.
Expanding the Use Influence sets it to active. It reveals a value slider then.
Influence
The influence factor.
Restrict Frame Range
Expanding the Restrict Frame range sets it to active. It reveals some value slider then.
| Entry | What it does |
|---|---|
| Start / End | The start and end frame of the generated curve. |
| In / Out | Fade the curve in or out for chosen frame numbers. |
Cycles modifier
Add a cyclic motion to a curve that has two or more control points. The option can be set before or after the curve.
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 Bezier 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.
Before Mode
Set the cycle mode before the first keyframe.
Count
Maximum number of cycles to allow before first keyframes. A value of 0 means infinite.
After Mode
Set the cycle mode after the first keyframe.
Count
Maximum number of cycles to allow after last keyframes. A value of 0 means infinite.
Use Influence

Noise modifier
Adds noise to the curve.
Blend Type
How to blend the noise with the curve.
| Entry | What it does |
|---|---|
| Scale | The overall size of the noise. The bigger the value the less frequent the noise. |
| Strength | Adjust the Y value of the noise. |
| Offset | Time offset of the noise. |
| Phase | The random seed for the noise. |
