Trying to understand where flair can fit in a vtuber pipeline

Hello peeps, I have recently discovered flair and I can see the tremendous potential it has in potentially making vtubing models absolutely phenomenal.

However my understanding of how it can fit in a pipeline/workflow is very limited.

From my understanding for anything to be stylized with flair, it would need to be rendered directly on maya?

Or is there something that I can do to adapt the results from this rendering plugin onto other tools like unity or warudo?

I honestly would love to have the watercolor style that is doable by this plugin everywhere. It's absolutely amazing. Like a dream come true.

Apologies if my question is incredibly basic.
