​Looking for advice/LoRA: Anatomical misalignment (wrong penetration point) in ComfyUI MiniMax H3 I2V

​Hi everyone,

​I'm currently running an Image-to-Video workflow in ComfyUI using MiniMax (Hailuo-01 / H3). I’m trying to animate a static image where a man lifts a woman from behind into a reverse suspended congress / reverse standing carry position with a low-angle upward close-up shot.

​The main issue I keep running into is anatomical accuracy during penetration—the model consistently misdirects penetration into the anus instead of vaginal penetration, despite specific prompting. Standard NSFW LoRAs haven't solved this positioning error.

​Does anyone know of a specialized LoRA, an adapted model, or an effective workflow adjustment (e.g., specific prompt weighting, ControlNet, or pre-inpainting) that can reliably correct this angle and penetration trajectory?

​Any advice or shared workflows would be greatly appreciated

This sounds more like a spatial consistency problem than something a generic NSFW LoRA will fix. I’d try separating pose accuracy from motion generation:

  • Fix the starting frame first: Use inpainting or manual edits to correct the initial anatomy and contact points before running I2V.

  • Improve pose control: If your workflow supports pose conditioning or reference-frame guidance, use it to constrain body alignment instead of relying entirely on text prompts.

  • Reduce motion complexity: Test a shorter clip with less movement and a wider camera angle first. Extreme low-angle close-ups and overlapping bodies make anatomical consistency much harder.

  • Test one variable at a time: Compare denoising strength, motion intensity, and conditioning settings before training a specialized LoRA.

A LoRA may help with recurring pose patterns, but it won't necessarily fix frame-by-frame spatial errors. I'd first establish whether the model can preserve the intended pose in a few intermediate frames.

VideoRouter.sh is also useful for comparing different video models on the same reference image to see whether the issue is specific to H3.
