v1.5 Update

Introduction of two new detailers: hands and feet. You also get a new negative prompt in the UI as well as strength values (denoise) for each detailer at the bottom of the interface. I still recommend using GonzaLomo XL 6 but you can swap it with your favorite SDXL model.

Note: The latest version of ComfyUI will turn on Nodes 2.0 by default. This breaks some of the custom nodes used in this workflow. As Nodes 2.0 are still a beta feature in ComfyUI, I'd recommend turning that option off for the time being.

Overview

A fast and efficient workflow using SDXL. You just load it, go to your extensions manager and click on the missing nodes to install them.

There's the 4x NMKD Siax 200k upscaler in there. You'll need it or any other upscaler that you like to use.

The detailers use bbox detectors. I recommend getting the YOLO ones (both v8 and v9) but you can change that or not use the detailers at all.

I didn't add any LoRAs but there's a LoRA loader ready to go.

What I usually do is bypass everything (upscalers and detailers) using the panel on the left as these add time to each image generation. I generate a bunch of images (about 10 secs per image on a Mac Studio M4), and once there's one that I like, I'll use its seed and regenerate it, this time with all the upscalers and relevant detailers turned on.

The film grain node is turned off by default as this will double the generation time but sometimes it's just what your image needs to go from good to great.

There's a model that I recommend using but you can use the one you prefer obviously. Just don't forget to set the correct parameters in the sampler.

The prompt handles wildcards too. You can use the {blonde|black|red} syntax when generating images.

Don't hesitate to leave any question/comment below and I'll answer it as best as I can.

Cheers.
