    Flux.2 Klein Mix Workflow

    Edit up to 3 images or Text to Image. Support for 3 different Controlnets, Inpainting and Outpainting. Node for easier selecting image sizes and Aspect Ratio. Uses 3 different Flux2 Klein Enhancer nodes, but you can easily bypass them if you do not what to use them but can be used for increased consistency or making your prompt have more impact. Color matching and things small things to try and make a consistent Image edit.


    V3 is almost a complete remake compared to previous version. With the main goal to try and use more commonly used Custom Nodes or ones that are easy to install to not break things. But many things have changed while I have tried to keep the original design. The workflow has several notes to try and help with things. One thing to note for v3 that is not obvious is setting any Mpx value to 0.0 will keep the original image size.

    There is no Negative Prompt as is not officially supported, and even if it works with the Base model (but still no official support) it does not work well enough, write a better positive prompt instead..

    All custom nodes used:
    Essentials
    Rgthree
    Easy-Use
    Impact Pack
    KjNodes
    GGUF
    Controlnet_aux
    LayerStyle
    ArtVenture

    Below Does not have any requirements making for an easier and safer install:
    Inpaint-CropAndStitch
    ModdedNodes
    Comfyroll
    ControlAltAI
    Flux2Klein-Enhancer

    Note that V2 and V1 do not use the same custom nodes, and are harder to use because of that..

    Feel free to criticize, comment or ask questions.
