How to align physical body with animation?

Question

Hello friends! I imported some models and animations from external source. Create inherited scene from the model so I can associate animations (from animation library) with it. The problem is some animations drastically changes the position of the model so I’m looking for advices on how to align them nicely. For example:

I have a CapsuleShape3D for the model. The model is imported and type changed to CharacterBody3D. When crouch animation is playing, I can reduce the height of the capsule and lower it to keep grounding. However, when jump animation is playing, looks I have to figure out how high the animation moves then sync it to the capsule. I think I can use BoneAttachment3D to get out the height (though I haven’t tested) but I really wondering if there’re some nice and clean way to do it.

Thanks!

OK, found solution.

I saved animation to external file then edited key frames to offset the unnecessary movement.

In my case, what I did:

Deleted key frames on Hips positions when model is in the mid-air;
Add a new track to call func which applies an UP velocity on the physical body:
