>>2960813After messing a lot, this was the best inpaint I could get.
It changed the original red color for a brighter one, but at least completed the missing straps. So, from what I learned the only masked gave better results but I needed to pump the resize to 1024x1024 (instead of the default 512) and pump the mask blur numbers to around 20.
I used the same sampler, schedule and steps that I used in the original pic, as well as the same seed.. is this ok? Changing it seemed to be giving me worse results.
