Boss 3 Character Animation Stutter in Unreal Engine 5
I would like to know how to resovle this stutter in this character animation sequence, how to identify whats causing this issue.
let me see if i can help you with this problem, @DevHassan9824
i am not a blender expert but in maya when i export a fbx for animation and when i bake it, i select it to generate more frames than the ones that are just animated. i.e. it has several keys between each frame. to make sure of more precision and not to let the program interpolate.
in the video i can see that even the hip bone is vibrating.
So. i think the first thing we could do to be sure, is: open the FBX exported in blender again, and we should check the animation curve of the hip or the root. to see if it is not in step or with irregularities.
After corroborating this, another thing I usually do when I have accuracy problems is to add the following structure to my skeletons.
you should be left with a structure of root- >Hip but also root->IK_foot_r
these IK_foot_r and IK_foot_l bones should be constrained to your original feet and follow it. so these IK’s should follow the leg bones in the animation.
Then you could put an IK system in Unreal to overwrite the vibration on the foot, so that the whole fk leg follows these IK_foot bones.
it usually happens that the more bones there are intermediate between the root and the final bone, the compensation in rotations and translations that makes each bone before the end (the feet and hands usually) generates many irregularities and noise. for that reason many times you use the structure that I send you and then you use an IK in Unreal to avoid that shaking.
let me know if any of these ideas are useful or if we find any other symptoms of the problem.
Best regards!
