Q21 Version

Nothing has changed dramatically from the FK9 version to the Qwen 2.1 version. I've simplified the image inputs and the actual sampling subgraph since the Q21 encode node just works really well (not latent reference nodes which makes me happy). I've only tested it with character sheets and with a relatively simple character, but you can scale it up as much as you want. I do only one input because Q21 seems sensitive to the amount of inputs you give it. I've built a Character Sheet which you can use with this work flow to build out fairly robust datasets for lora training.

Q21 works WAY better than FK9 with regards to this. I've added in the ability to use a turbo lora but you really don't need to. 1mp 30 image datasets take about 8 minutes to make. There are ghosting issues which I don't know how to fix that other than to just weed them out after the fact.

Update:

I've replaced the version I uploaded this morning with a version that has prompts better optimized for Q21, along with settings that I've found that work well. Below is the prompt list:

Fk9 Version

Fairly straight forward. You can use this workflow to automate dataset creation. Default is set to 30 images but you can of course customize to your needs. Here are the directions:

Version 2 Update: The version 2 work flow now includes a wildcard node that will randomly change the background and the lighting of the image. Can add more or take some away if you wish. You can run it multiple times for more variety. I'd recommend doing it for alternate outfits.

Directions

Step 1 - Load 1 to 3 reference images. Adjust reference images if desired.

Step 2 - Adjust the "Ref Image #" panel accordingly on the FK9 run subgraph. This is scalable so if you want more than 3 (don't know why you would) it is possible.

Step 3 - Input the master prompt. This will guide basic details like style and lighting as well as letting you fine tune certain elements.

Step 4 - Adjust angle prompts if desired. I have 30 in there now. Each line will function as its own run so if you add more or remove some adjust your batch number.

Step 5 - Set output folder

Step 6 - Hit run

Best practices:

If possible I like to make a character reference sheet of three to four views at 4 megapixels, then a close up headshot. Those two work well as references.

You can adjust outfits and accessories in the Master Prompt, but I think you're better off making a new reference sheet with those changes instead of hoping all 30 outputs are consistent. Obviously adding in a third reference image with that adjustment will help.

In theory you could add different backgrounds and settings in the Angle Prompt section. I chose a more neutral approach because that has tended to work best for me when training character loras.
