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 graph | On the graph, move the mouse while middle clicking. |
Horizontal scaling | On the graph, hold down Ctrl and scroll the mouse wheel. |
Vertical scaling | On the graph, hold down Shift and scroll the mouse wheel. |
Add key frame
In the case of a three-dimensional vector
X | On the graph, press the X key |
Y | On the graph, press the Y key |
Z | On the graph, press the Z key |
In the case of a color
Red | On the graph, press the R key |
Green | On the graph, press the G key |
Blue | On the graph, press the B key |
Alpha | On 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.
