Hi,

It feels like this is a real newb question but when adjusting fcurve handles how can I adjust the length of only one side?
Seems pretty stupid that lengthening one handle also changes the other one. 

I know you can ctrl-shift and drag but that breaks the angle.

Am I missing something obvious somewhere?

Cheers,
P

Hi P.,

With my settings* I use Shift + Command.

(* Preferences: Input Devices> Control-click for right click)

Please have a look here:

The following keys can be used when editing tangents (Shift also works in conjunction with Ctrl/Cmd and Alt):

Shift: Tangents will be broken; left and right tangents can be edited separately.
Ctrl/Cmd: Only the tangent length can be edited.
Alt: Only the tangent’s angle can be edited.

The effects of using these keys can be limited by opposing settings (e.g., applying the Ctrl-key will not override the Lock Tangent Length option).

Is this working for you?

All the best

Thanks for the reply as always, Dr S.

Unfortunately I can’t seem to find a combination that works, but it feels like such a basic thing I can’t believe there’s not a way to do it.

Hi patrick.nethercoat,

Here is a screen capture; please let me know what is working or not on your side so we hopefully get it working for you.

Thanks for that. It seems I didn’t describe what I’d like well enough.
This (https://app.frame.io/presentations/f2d79d25-eeaa-4d07-8155-b8646f5d3939) is the behaviour I’m looking for.

Hi P.,

Thanks for that. Shift-key as before, to break the relationship between the two handles, but you like to keep the direction of the two.

In the F-Curve Timeline> Key> Keep Visual Angle.

Cheers

Ah, that’s mega. I knew there must be a combination of things I hadn’t tried yet.

Thanks once again, mighty Sensei.

You’re very welcome, P.! (Names: I use the avatar name or what is used in the post.)

Thanks for the video; that helped a lot to find the answer.

My best wishes
