How to recreate:
1)enable “Auto first key”
2)create shot camera clip and create a shot.
3) click on random point in timeline to enter REC mode
4) Move the auto created diamond key
At first it seems to be fine, but try to create a second key now and you’ll have 3 keys!
the auto key is not ignored by the editor!
Even creating first key yourself causes same issue.
P.S.
what type of animation is “diamond” key? like linear, smooth, constant… what is diamond one?
I tried replicating this, but it works here as expected :/
After moving the auto created first key, another key is not created automatically anymore (which is how it should work).
The “Auto-First Key” basically, will only create a keyframe if one does not exist already.
Are you using the latest version from the Asset Store (1.45)? You can check the version you are using at the Slate Toolbar at the top right and next to the settings “gear” icon.
The Diamond shape key, is “Editable/Manual”. The tangents of the keyframe are free to move and is neither really linear, smooth or constant. You can change the default key interpolation in the settings by the way. The relevant setting is named “Initial Keyframe Tangent”.
