How to make a smooth transition between looped animations in Live2D?

[gofa4a]

Live2D animation has a default_fade parameter, which when set to "0" makes the animation loop if it has no seams. This is what I need. But how do I make a smooth transition from one character emotion animation to the second? If the value is "1" - then the transition between animations is perfect, but then my looping animation does not work correctly when replayed. If the value is "0", then the looped animation works well as it should, since it is seamless, but when switching to another emotion, an unpleasant jump occurs (there is no smooth transition). Is there a solution to my problem so that a seamless animation and a 1 second fade transition between animations can be used? It might be worth separating these 2 parameters "current animation" and "transition between animations" so that we can set the values in both cases.
