A clean workflow ideally suited for SD models . It includes:
a. Detailer pipe (to fix faces)
b. Second Pass
c. Upscaler
The workflow uses:
1. Wildcard node (because I just love wildcards)
2. Anything Everywhere (make things neat and tidy)
3. Fast Groups Muter (in case you want to skip the upscaler)
Newer checkpoints are great but I still think you need detailers to fix the faces.
