Fooocus Facial styles Problem can anyone help?

[mrai2025]

I've watched every YouTube video I can find on how to change facial expressions in Fooocus, but I keep hitting a brick wall.

I want to be able to modify my subject's face to show emotions like laughter, sadness, or anger. When I create a new subject, this isn't an issue — I can simply add a prompt, use Pyracanny with a Grid head, and the expression comes out perfectly.

However, the problem arises when I try to use the original face I initially created with a neutral expression — the typical model face. When I use this face in the faceswap and apply Pyracanny for expressions like laughter, the result remains motionless and expressionless.

Is there something I’m doing wrong, or is it not possible to use the same face model I initially created while changing the expression?

Looking forward to your advice, and I hope I can overcome this obstacle.
