Be sure to read these usage notes. This is a bit weird in spots.

Ask Flux to make a crying adult and you get a "smiling through the pain" picture. This fixes that and works for both men and women.

Use with other LoRA: If you use this with another LoRA that had faces included in its training, the crying effect might be reduced depending on the the expressions on those faces. If it was trained on all smiling faces, that will be difficult to overcome.

Very Important on teeth: This training used pictures of babies crying. The only artifact of this that I saw in testing was that it often gives the adult messy baby teeth, so you'll want to prompt "perfect teeth" to get around that.

Trigger: "(person) is in great pain and crying hard"

LoRA strength: This Lora starts to disassemble and produce poor quality faces at high strengths. I recommend a strength of 0.9 or less to avoid this.

Custom Faces: It's possible to use custom faces just depending on the custom face LoRA.

Notes: I couldn't get flux trained on tears, but may come back to that later.
