FAQ:
- Using txt2img
- Find an image to reference, load it into 2 ControlNets
- This generally helps the prompt out a little and helps to avoid mutations but comes at the expense of generating a completely original image
- Load the image into Canny/Openpose, enable pixel perfect
- Canny if you want to just copy the image
- Openpose if you want to copy just the pose but replace everything else
- Load the image into Depth, enable pixel perfect
- self-explanatory, helps add depth to the image
- Find an image to reference, load it into 2 ControlNets
- Create your prompts and set the image size
- Use 512 for the lowest dimension
- Set the sampler to DMP++ 2M Karras
- Set samples to 25
- Enable Highres.fix
- Upscaler: 4x_NMKD-Superscale-SP_178000_G
- Highres Steps, 10
- Denoising Strength, 0.4
- Upscale by 2
