How to fade in from OneShot into StateMachine Animation Node

Godot Version

Question

Hi, I’m quite new to 3D animations and I have this AnimationTree setup where the root state machine is for movement animation, and when the character performs an attack it uses one of the OneShot nodes to play the animation:

I’m switching between two OneShot nodes so that two OneShot Animations can blend with each other. However, I cannot find an option to fade in into movement animation from a one-shot animation.

I don’t want to add fade-out for my one-shots as they represent accurate movement and fade-out will affect their last 8 frames or so. (For example, blending from one shot dodge move into walk can lead to walking forward for the last 0.2 sec of the dodge animation)

Any suggestion on how do I restructure my animation tree so that I can fade into movement from one shot?
Please let me know, thanks.
