I know you're working hard and likely still have work to do on the Modern pack. I just wanted to suggest an improvement I’d like to see, building on your existing effect extraction feature—specifically for the halos (outlines).
As it stands, I believe I have to extract multiple versions of the same character if I want a halo to appear only during a specific period, and I assume that means generating all the animations for every version of the character.
That said, I’m not sure if it’s possible to extract halos as easily as a standard effect.
Thanks for your work!
