Creates ripples/bounces on ass.
Just a wan 2.2 test .
Use with other loras .Bump LOW lora to 1.1-1.4 if not enough ripples added , could be just seed issue.
ass ripple. ???????? + back view / side view / from behind
Example was created with suggested ones below + lighting 2+2 steps.

Few stylized vid examples were used so it might not work from every angle.

Suggested behind/side doggy poses.

Change vid output to 20fps for more dynamic movement if needed.

Might train more poses on top later.
