Regional Prompt Denoise Can Cause Step Issues #251

Open sedetweiler opened 11 months ago

sedetweiler commented 11 months ago

When you set the denoise to something like .6, it will work on the region as expected, but will also take the step count way over the specified number and will cause the rest of the image to suffer from overworking. image

Mentioning 0.6 appears to signify i2i. Once it exceeds 0.6, the influence of noise is expected to become stronger than that of the original image. An increase in the influence of noise implies that the structural impact determined by the seed becomes stronger. This might lead to a phenomenon of contention.

I have created a workflow that allows you to set up conditioning in a manner similar to the Regional Prompt. Essentially, It is a wrapper of the Conditioning Set Mask in a more convenient style. While there are some functional constraints compared to the Regional Sampler, it will generate much more natural images.

I had the denoise set at .6 to help with coherence over the initial face. However, the rest of the image gets so damaged from the process. I wish that overlap setting worked to protect the rest of the unmasked assets.
