Chinese farbic Embroidery birds
I did an embroidery exercise. For this kind of complex pattern, I think it is very convenient to select in Photoshop. Selecting can be drawn with pencil tool, or done with hard edge selection, so that it is less likely to make mistakes when SD detects selection.
here is the node https://shining1.gumroad.com/l/jlryyc
Making these selections in Photoshop is much easier than SD. The four channels can be combined into a picture and imported into SD.
I made a gray detection node, which can detect 20 levels of gray mask. RGBA can have 80 different masks with four channels. This is handy for making complex patterns.
Each selection only has a small part of the whole image. I modified the node of CROP_GRAYSCALE to cut out the selection first, generate the embroidery pattern, and then restore it. The resulting pattern is more delicate and the calculation is more efficie
The gradients use the gradient_axial node, which has two coordinate points and is handy for making color changes.
