make animation loop forward and backward (ping-pong)?

[baobao4435]

hello.
this is serious…
I would like to cut an animation and make it to loop in a ping-pong way.
here’s demonstration:

so I downloaded the asset from epic store.it doesn’t contain an idle animation.

I want to take a short part of one of the animations to simulate the idle.

I know how to cut the anim.but don’t know how to make loop forward and backward together.

I’m not familiar with control rig or other artists tools.
so step by step guidance is expected
cheers!

Yes you can edit the animation. But there’s also this option:

You gotta add a notify to your anim montage to make the transition smooth though. Also make sure you got the default slot connected to your main out pose in the anim graph of your animation blueprint.

(the value 10 you see there as the starting position on the second play montage node is the total frame count in my example animation btw)

Hope this helps!

hey
it’s not montage or anim BP…
I want to edit the anim asset itself so that I get a new animation.

In that case, you can duplicate your existing animation, set the play rate in one of them to -1, and combine them in an animation composite

I hope I managed to explain everything clearly, but sorry if this answer doesn’t suffice, I just got off my PC so can’t send a video or screenshots showcasing the implementation.

Or you can do that in a 3D editor like Blender and import the combined animation.

yes it’s totally sufficient .

I need this part

@VisAgilis

combine them in an animation composite

never mind ,there’s no hurry.
You could post screenshot whenever you feel like.

Here’s the documentation for it:

Animation Composites in Unreal Engine | Unreal Engine 5.5 Documentation |...

You just create one and drag & drop those 2 duplicate animations (one of which is reversed)

wow.thank you.this really helped a lot.I can edit a lot animations.
previously I just used a single pose to represent an idle because of I didn’t know how to combine animations.

perfect!no artifacts at all.love it.!
