So in my project, i am animating a propeller that will rotate for a specific amount of time then slow down and finally stop. In matinee i can animate it were it rotates perfectly fine, but if i convert from Matinee to Level sequencer, the prop still rotates but then does a 180 in the yaw direction ( i am only rotating it in pitch) once during each full rotation.
I tried starting fresh in level seq but i still cant find anyway to have it rotate 360 fully.
I know in Matinee in order to get this to work i had to enable Quat Interpolation, which i belive in level seq is just setting the key frames to Linear, but still does a back flip.
Anyone have any ideas?
(Prop in Matinee)
(Prop in Level Seq)
I don’t use the sequencer, but that looks exactly like a problem I’ve had in blueprint. There’s usually an option in the rotation animation ‘shortest path’, something like that. Can you see it?
EDIT: Meh… can’t see it there, it may be to do with the key interpolation options…
On new transforms Quaternion interpolation (which will always find the shortest path) is disabled by default on Transform tracks. Perhaps in the Matinee → Sequencer conversion it is being re-enabled? You can check by right clicking on your transform section and going to the Properties section.
To make it animate past 180/360, you may need to just change the value in the Transform track to go beyond 180.

Good news, i figured it out!
Il write the numbers i used for future reference for people.
So after ticking the Quat option, it did indeed stop doing a reverse flip, but then it would rotate 180 degrees, then reverse the direction for 180 degrees ect.
Took some Time to figure out, but it ended up being to change a single number for the rotations, il list them below (To make a rotation, it takes 4 key frames)
Rotation
X Y Z
180 1 -180
0 -90 0
0 0 0
0 90 0
After you can get the propeller, tire or whatever people use to rotate 360, just copy.paste these 4 key frames and it should work perfectly fine.
Thanks for helping me out!
Edit: Formatting broke the degrees for rotation, uploading image instead.
