Cycle FCurves

[Stephan Dube]

Id like to know if it is possible to have a cycle (loop) on a keyframe?
for example if I have 2 keyframes of opacity (100% and 50%) and I want it to do a cycle so during the entire animation it would do it. Im sure there is a way to do it in expression but Im not that savy, for now Im uding the good old copy and paste but Im sure there must be a better way
thanks

You’d need an expression.

There are 2 that could be directly applicable to your situation:

loopOut();

and

loopIn();

The first will loop the values after the last keyframe, the second will loop the values before the first keyframe.

There are several different kinds of loops:

loopOut("cycle");
loopOut("continue");
loopOut("pingpong");
loopOut("offset");

Here’s a video that should help illustrate the differences:
