Trouble Creating Donut Animation in Unreal Engine

Summary

I’m new to Unreal Engine and wanted to experiment with making a chocolate donut animation that could be used for my blog. The 3D model looks fine, but when I try to set up the animation, it either doesn’t play or gets stuck. I’m not sure if I’m missing something with the animation setup or if there’s a problem with the way I imported the donut model. Since I don’t have much experience with Unreal, I’d really appreciate some guidance on what steps I should follow to get the animation running smoothly.

What type of bug are you experiencing?

Steps to Reproduce

Open Unreal Engine and create a new project.

Import a 3D model of a donut into the project.

Try to create a simple animation for the donut (for example, a rotation or movement).

Set up the animation timeline and apply it to the donut model.

Play the animation in the viewport.

Notice that the animation does not play correctly or sometimes gets stuck.

Expected Result

The donut animation should play smoothly in the viewport. For example, if I set it to rotate or move, the donut should show that motion without freezing or stopping.

Observed Result

The animation either does not play at all or it freezes partway through. Sometimes the donut stays static even though I’ve set up the timeline for movement.

Platform

Unreal Engine editor (using the built-in viewport to test the animation).

Operating System

Windows 10

Hello, Welcome to the Forums.

I’d first double check the length of your sequence. (Maybe it is stopping because the keyframes are not matching the overall time)

Also try changing the keys to linear interpolation. (Otherwise it will slow/ease at start/end)

There are many “how to animate with Sequencer” videos out there, so watching a few more should set you straight.
