Before You Begin:

Thank you for considering supporting us! Since these workflows can be complex, we recommend testing the free versions first to ensure compatibility with your system. We cannot guarantee full compatibility with every system that's why we always provide the main functionalities for free!

Please take a moment to read through the entire guide. If you encounter any issues:

  1. Check the troubleshooting section at the end of the guide

  2. If problems persist, visit our Discord's #need-help channel and use the search function—many common issues have already been resolved

  3. If you cannot find it there ask and we will try to help you. give as much information as possible. Include screenshots, the error.

1 Install ComfyUI

  1. Download ComfyUI: https://github.com/comfyanonymous/ComfyUI

  2. Extract the folder to the location where you want to install ComfyUI.

  3. install git https://git-scm.com/download/win

    • standalone version

  4. Download ComfyUI Manager: https://github.com/ltdrdata/ComfyUI-Manager

  5. Extract it, put it into your ComfyUI directory and run it.

  6. After it’s done you can run ComfyUI by clicking run_nvidia_gpu

To help you with the installation, take a look at this short guide from MDMZ:  https://www.youtube.com/watch?v=E_D7y0YjE88

Congratulations, you installed ComfyUI! 🥳 To use my workflows you’ll need some extra models and extensions, but it is super easy to install them!

In the next step I’ll show you where to get and put the models. If you’re having issues check if you can just install them via the ComfyUI Manager. Just search for them and when you click “Install” they will be put in the right directory.

2 Character Sheets with SDXL

Get the workflow here 👉 https://www.patreon.com/posts/free-workflows-113743435

Drag and drop the .json into your ComfyUI Interface.

Go to ComfyUI Manager > Install missing custom nodes > install all of them > Restart ComfyUI

If you have problems with the Flux workflow, make sure you are using the latest version of the workflow! (v05)

Download the Models:

Download these models and put them in the corresponding folders:

  1. Checkpoint: https://civitai.com/models/293331/wildcardx-xl-turbo

    📁 ComfyUI_windows_portable\ComfyUI\models\checkpoints

    You can also use any other SDXL checkpoints for all the workflows. I recommend Turbo or lightning ones though for faster generation time especially for the video workflows. You can find more models on CivitAI.com. Check the example images for the settings and match them in your KSampler!

  2. SDXL CONTROLNET: https://huggingface.co/thibaud/controlnet-openpose-sdxl-1.0/tree/main

    (OpenPoseXL2.safetensors)

    and: https://huggingface.co/TheMistoAI/MistoLine/tree/main

    (mistoLine_rank256.safetensors) <- For the Advanced version!

    📁 ComfyUI_windows_portable\ComfyUI\models\controlnet\sdxl

  3. UPSCALE MODEL: https://openmodeldb.info/models/4x-ClearRealityV1

    📁 \ComfyUI_windows_portable\ComfyUI\models\upscale_models

Check out the official FLUX Installation guide for ComfyUI here:  https://comfyanonymous.github.io/ComfyUI_examples/flux/

  1. Drag and drop the .json into your ComfyUI Interface.

  2. Go to ComfyUI Manager > Install missing custom nodes > install all of them > Restart ComfyUI

    This should install “ComfyUI-eesahesNodes” from ComfyUI manager (contains InstantXFluxUnionControlNetLoader)

  3. MODEL https://huggingface.co/black-forest-labs/FLUX.1-dev/tree/main

    flux1-dev.safetensors or https://huggingface.co/black-forest-labs/FLUX.1-schnell/tree/main

    📁 ComfyUI_windows_portable\ComfyUI\models\unet

  4. CLIP  https://huggingface.co/comfyanonymous/flux_text_encoders/blob/main/clip_l.safetensors

    and

    https://huggingface.co/comfyanonymous/flux_text_encoders/blob/main/t5xxl_fp16.safetensors

    📁 ComfyUI_windows_portable\ComfyUI\models\clip

  5. VAE https://huggingface.co/black-forest-labs/FLUX.1-schnell/blob/main/ae.safetensors

    📁 ComfyUI_windows_portable\ComfyUI\models\vae

  6. CONTROLNET MODEL: https://huggingface.co/InstantX/FLUX.1-dev-Controlnet-Union/tree/main

You can get the models via the ComfyUI Manager:

You can also use the ShakkerLabs models, which are meant to be newer and improved versions of InstantX. Though in my testing, I actually got better results with InstantX.

4 Training a LORA

For Training I recommend using FluxGym via Pinokio.

You can also train Loras online via Replicate for example. Cost 2-5 Dollars for one Lora.
