About

This LoRA is intended to generate an undressed version of the subject (on the right) alongside a clothed version (on the left). Precede your prompt with the "onoff" keyword, and then describe your subject (including any clothes you wish to appear on the lefthand image).

Versions

The latest version 4.0 takes advantage of more recent optimization enhancements and seems more reliable than previous versions. However, it was trained at 640x640 pixels, and it also tends to oversaturate and increase the brightness of the image if you use it at a smaller resolution. Please let me know how it works for you.

v4.0 - Best at 640x640. Used the dynamic learning rate from the Prodigy optimization settings and a more controlled dataset to more reliably produce the desired configuration.
v3.26 - Best at 512x512. Increased the size and quality of the training set and captions compared to previous versions, but used a smaller network rank (still larger than version 1.x) to improve overall control
v2.39 - Larger training set than 1.x, larger network rank, can handle more subjects and styles. Might work better for more heavily tuned models like CyberRealistic.
v1.28 - Original version, best suited for individual female subjects
v1.50 - More heavily trained original version if you have trouble getting 1.28 to work with your prompt.

If you're looking for the right hand image to be wearing underwear instead of nude, try the dedicated On/Off (Underwear) LoRA.

Tips for best results

Prompt

Precede your description of the subject with "onoff," and mention the subject's clothing in the following sentence. Adding "side-by-side photo" or "split screen" can help steer your base model toward generating the right shapes for the LoRA to take hold.

You can try "onoff couple" and "onoff male" to work with subjects besides individual women.

Weight

In most cases the models should work at the default weight of 1. If the concept is not being applied on your image, and you've already tried adding "helper" phrases like "side-by-side photo" and "split screen," first try increasing the weight of the "onoff" keyword in the prompt rather than the weight of the LoRA; both methods can work, but an overcooked LoRA model is likely to warp faces.

Speaking of which, I recommend using high res fix for better faces.

Control Net
