Nsfw Upscale
Specifically for high frequency details.

Klein can upscale obviously but does so horribly, over saturates the image, with too much contrast, too much unrealistic detail etc, if prompted.
This lora tries to keep the model toned down as it upscales and adds realistic micro details (in most cases, its not perfect).

Trained on high quality nsfw explicit images.

Required:
Add the LTXVpreprocess node, it adds a predictable artifact to the image, that this lora was trained on to fix (native comfy node). ImageScaleToTotalPixels to --> 2MP.

Trigger: enhance

There should be a workflow embedded in the image. Pretty straightforward though

Note: The rank is fairly low, probably needs to be retrained with a higher rank, will get to it at some point but its fine for now. And it was mostly trained on caucasian as thats my preference so not sure how well it does it other skin types.

It does shift the image a bit too, probably a bit overfit.
