### Noise Plus Blend
This node will generate a Gaussian blur noise based on the dimensions of the input image and will blend the noise into the entire image or only the mask region.<br>
**Issue:** Generated faces/landscapes are realistic, but during upscale, the AI model smoothens the skin or texture, making it look plastic or adding smooth fine lines.<br>
This node will generate a Gaussian blur noise based on the dimensions of the input image and will blend the noise into the entire image or only the mask region.
**Issue:** Generated faces/landscapes are realistic, but during upscale, the AI model smoothens the skin or texture, making it look plastic or adding smooth fine lines.
**Solution:** For upscaling, auto segment or manually mask the face or specified regions and add noise. Then, pass the blended image output to the K-Sampler and denoise at 0.20 - 0.50.
