When using Redefine, mode please allow Face Recovery options to be enabled when Creativity is set to 3 or above.
Skin texture results are consistently poor when Creativity is set to 2, and hair texture results are consistently bad when Creativity is set at 3 or above. I currently save images with both settings, then use Photoshop to combine the photos to produce a desired outcome. It seems like Gigapixel AI should be able to manage this.
