F-Curve

Overview

This is a feature that lets you automate frame-by-frame values over time by defining curves in a graph.

How to use

Display Graph

When you specify the F-curve for each item (position, rotation, etc.), their graphs will be displayed in the F-curve window.

Movement / Scaling of Graphs

Move graphOn the graph, move the mouse while middle clicking.
Horizontal scalingOn the graph, hold down Ctrl and scroll the mouse wheel.
Vertical scalingOn the graph, hold down Shift and scroll the mouse wheel.

Add key frame

In the case of a three-dimensional vector

XOn the graph, press the X key
YOn the graph, press the Y key
ZOn the graph, press the Z key

In the case of a color

RedOn the graph, press the R key
GreenOn the graph, press the G key
BlueOn the graph, press the B key
AlphaOn the graph, press the A key

Select key frame

You can select by left clicking the mouse.

Move key frame

After selecting the key, you can move it by moving the mouse while holding down the left mouse button. In the same way, you can also move the handles that control the curves.

Delete key frame

After selecting the key, you can delete it by pressing Delete.

Parameter

Frame

Set for each key. Specify the frame of the key.

Value

Set for each key. Specify the value of the key.

Type

Set for each key. Specify the interpolation method between this key and its neighboring keys.

Start

Set for each graph. Specify how values before the left edge of the graph should be generated.

End

Set for each graph. Specify how values after the right edge of the graph should be generated.

Sampling

Set for each graph. When actually playing back, specify how many frames to use as the resolution for interpolation. The smaller the value, the more accurate the result will be to the actual shape of the graph.

Left X/Y

Set for each key. Specify the position of the left handle of the key's curve control.

Right X/Y

Set for each key. Specify the position of the right handle of the key's curve control.

Max/Min Offset

Set for each graph. When using values, offset the range, randomly shift the value up or down the graph.
