Can't edit graph editor handles

[Anonymous]

For some reason I can't edit the curve handles in the graph editor. When I try and select a keyframe, nothing happens.

The handle's are circles instead of triangles or squares

Have you tried creating a new empty scene and see if it does the same thing? A screenshot would help.

Also, check if your animation channel is locked or something similar. Make sure the color is red.

I'm attaching a recording. Thanks so much for replying, I was thinking nobody could help!

Hi,

Off course!

So have you tried with an empty scene while animating a cube for example?

I'm using Maya 2019 so I might not get the same result than you. My keyframes are not even the same shape as you too. 

Have you checked the channel you are animating to make sure it's not locked or something?

I can't see your maya file anywhere in your last message...

Hi,

I figured it out.

It's because your curve is handled in Quaternion right now so there's no handles.

You have to change the Curve mode by going Curve > Change Rotation Interp > Independent Euler

This is from the documentation:

Key types

Diamond key: non-weighted tangents  Square key: weighted tangents  Circle key: a key on a quaternion curve (no tangents) Hollow key: A new key with 'automatic' tangents. The key is filled when you adjust the tangents to show that it has been edited.

Forums won't let me attach the file, so here is the google drive link:
