LoRAs for anatomy fine-tuning - PornX Support Content

A LoRA (Low-Rank Adaptation) is a small model that runs on top of your chosen model and pushes the output toward a specific look. PornX currently has two LoRAs focused on anatomy accuracy.

How to apply a LoRA

Add the trigger directly in your prompt: <lora:NAME:WEIGHT>

NAME — the LoRA identifier (see each LoRA below)
WEIGHT — how strongly the LoRA influences the output. Range: 0.1–1.0. Best results typically fall between 0.3 and 0.8.

Example: <lora:64:0.6>, big breast, pink nipples — applies Better Breast at 0.6 weight with supporting trigger words. You can combine both LoRAs in one prompt. Keep total weight balanced — stacking two at 0.8 each tends to produce artifacts.
