Hi dear UE team! In animation assets when I trying edit sequence by rmb->Remove from frame “start” to frame “before”, the Editor does the same as Remove from frame “after” to frame “end”. It has begun after 4.16.1 update.
Hi All,
I see you’re both having this issue, but I’m unable to reproduce this on my end in 4.16.2. Are you still experiencing this?
If so, can you reproduce it with any animations in the Third Person Template Project?
No i cannot replicate it with a clean Third person Template. Also tried the Animations Starter Pack animations.
I believe it can be animations that has been retargeted where the root has been missing.
I have the same problem…
Hello, i’m having this issue aswell in 4.19.2. I’m trying to create crop an animation so it only has the last frame but he’s always keeping the initial frames, so it doesn’t matter if i pick Remove frame 0 to X or Remove from X to Last Frame.
This seems to have been fixed in 4.20. Please test it and close the issue if it’s resolved on your side.
Using 4.20.1 and the remove frame option doesn’t appear to do anything.
I’m having the same issue in UE5. I can’t remove the first or last frame.
same issue here, UE5
Still the same issue with UE5. Make trimming animation impossible
The culprit is
UE::Anim::AnimationData::Trim
this function experiences the last frame of doomed!
Instead:
UE::Anim::AnimationData::RemoveKeys
Works without issues.
Unreal team: fix UE::Anim::AnimationData::Trim or use RemoveKeys 
I think I’m still have this issue in the editor. Are the above C++ classes that you can use to make the fix?
