Pretty much only tested this with strength 1 and two pass and seems to work for T2V and I2V.

Also trained on audio.

Given its my first LTX2.3 lora and the first run result is much better than expected, especially given WAN isnt an optimal choice for this kind of concept.

Example prompts used:

a woman with long brown hair sitting in a chair. The background appears to be a room with a red wall and some wooden elements. The woman is smiling and looking directly at the camera as she gets slapped on the cheek by a hand entering the frame. Her head swings to the left following the impact and back fast while she appears turned on and is biting her lip. There is a black sofa behind the womans head. The lighting is somewhat dim, giving the image a warm, slightly reddish tone. There is a sound effect of a whip slap followed by a soft moan.

---

a woman with blonde hair. She is topless, with her breasts visible. Her eyes are closed, and she appears to be in a relaxed or possibly playful pose as she gets slapped on the cheek. Her head follows the impact of the slap and swings to the right and back with her looking directly at the camera smiling. Her hair also is in motion. There is a slap sound following the impact and is followed by a moan.

A woman with short, dark hair is shown. She is shirtless and appear to be in a bathroom, as indicated by the tiled floor and a wooden structure in the background. The woman is looking directly at the camera. A hand enters the frame and slaps her cheek. She closes her eyes and her head follows the impact and remains fully turned to the side.. She smiles as the hand grabs her chin in a sensual way. Their expression seems to be one of contentment or relaxation. The lighting is bright, likely from overhead bathroom lights.With the impact there is a hard slap noise.
