Once Upon A Time...
It was another dreary day, the only sound is the rain occasionally splashing upon the window and the click of my PC power button. It was not long after that I ventured deep into the shadow realm, known as reddit and chub, searching for hidden treasures and rare gems known as character cards. Lo behold, I hath found them! But what is this? I must pay gold for these artifacts generated by magic? And they do not come with lore books, nor are they written by a master scholar, and NAY- they doth not ship with EMOTIONS?! I do not deny you the truth my friend, before my very eyes, in the very same same shadowland, I see these, very much the same, vile merchants protest against the very idea of mercantilism itself! What MADNESS?! It was by mere chance that I escaped these lands with my mind mostly intact. In time past, contemplating on how I could turn lead into gold, and slop into peak material- I tell you this, as any true friend would, the shadow realm folk are beyond redemption, but I may have developed a magical artifact that can take even the most mundane character card and turn it into a legendary item!

Description
Okay, okay, no more fucking around. What is this? An Anima workflow that generates high-quality Silly Tavern character expressions in just minutes. Gives you tons of options (portrait mode, background creator, low resolution, manual selection, additional prompt tags, etc.), yet, it's designed to be easy as just clicking "run" upon first load. In addition, it will generate sex expressions for all non-extreme positions, as well as combat poses.

Installation
Before you do use this, yes it's easy to use, but I am assuming you are familiar with ComfyUI, this really isn't meant for new comers.

PreReqs:

• [ Download ]: ComfyUI Manager (It allows you to install missing nodes)
  (Or: pip install -U --pre comfyui-manager)

• [ Download ]: Pixel Color Picker (It's not included in the ComfyUI Manager Repos)
  (Drop the PixelColorPicker.py into your custom nodes folder)

• [ Download ]: Easy-Nodes (For wildcards and style selector)

Download the included ZIP file and extract it to your ComfyUI directory.
(Contains wildcards and example character style sheet as well as the workflow)

Operation
It's set up to work out of the box. However, you do need to click on a character in the 'style selector' node. I supply 3 characters, they were just created for testing this workflow, so quality is in they eye of the beholder, but I assume you want to make your own characters, here's how you do it:

Go to ComfyUI/custom_nodes/comfyui-easy-use/styles and open the Characters.json (or make your own), use mine as a template and go to town. Use only character tags - no quality tags, no action tags, gestures, posture, poses, camera, etc.. Only use anatomy and clothing tags.

As for the rest? Read the tips, everything is pretty self-explanatory.

Since this is in prototype mode, you'll probably have to curate about 50% of the images and delete the ones that don't turn out well.

Questions

Is it perfect? No, but it's output will outdo 99% of other expressions out there. And, I have done my best to mitigate any limitations dealing with auto generation expressions.

Do I just copy the images to SillyTavern/data/default-user/characters/My_Character? Yes, maybe one day I'll make a bash or bat file to do metadata merge, renumber and automate it all, but for now, just copy the pictures into that directory, Silly Tavern will automatically register the pictures on boot.

What model should I use? Start with WAI - https://civarchive.com/models/2544636/wai-anima

How do I get Silly Tavern to use the extra expressions? Set expressions to Main API. Add custom expression for each one you want. (Personal note: Silly Tavern Expressions extensions needs to be reworked, it doesn't get a lot of popular emotions and it has duplicates that could be combined: grief/sadness/remorse, relief/realization. Maybe I'll offer a contribution to their git, or someone else can who's in their cool club.)

Completion Status? Danbooru has so many tags and getting the right combinations down will take some time. But give it a try, its pretty quick, just set the repeat to 50 or more and come back after a cup of coffee and check out your new expressions.
