Hi there!
I was wondering, how might I be able to create a new Expression in the Expression Editor using parameters from my Live2D model AND parameters from the Live2D Item I have attached on top of my model?
I basically have two forms for my VTuber model: and with each form, the attached Live2D Item needs to be changed along with the Live2D model - I know I could have the Live2D Item within the Live2D model file but it is not an option considering layering complications.. 
Trying to make a Twitch channel point redeem so that a redemption means both parameters from the Live2D model and Live2D Item is changed, so I hope there is a solution to this, thanks!
