I am very confuse that why AnimationSequence doesn’t support cubic or other smooth interpolotion ?

Hey there,
This setting is specifically for the interpretation of the interpolation of keys as a baseline sequence. Because the most common workflow for animation, whether it be from animating in engine or from external DCCs, includes animators controlling their tangents, this setting is there to provide the ability to read the curves as is or step the curves.
Do you have a specific use case you are looking for?

Apologies for the delay, Epic has been on summer break.
We do support it just not there, and not really the way you would expect. When we import animation we do our best to figure out the best sample rate, more than likely it’s the framerate of the animation. But you can modify the rate at which you sample the curve. In your image here, because your tangent adjust is between frames, you would need to change the sample rate to be higher to evaluate that in between data. You can see the option in the FBX import settings.

Hopefully that can help you out with your tool.

We’ll try increasing the frame sample rate, but we suspect linear interpolation might counteract the smoothing effect. Still, thanks for the feedback!
As shown in the image captured from Maya 2020 below, there’s a clear visual difference between the left and right sides, particularly in their distinct tangent settings.
When importing these animations into UE5, the version with ‘Spline Tangent’ settings in Maya appears much smoother. However, since UE5 doesn’t support importing tangent data, I’m working on extending a new feature to replicate this effect.
