Flux 1.0 dev txt2img, img2img and inpainting for ComfyUI version

[jordenyt]

1. Put under your <ComfyuiGW>/workflows folder, and update the LORA / UNET / VAE / CLIP in the file:

• flux_dev_img2img_api.json
• flux_dev_inpaint_api.json
• flux_lora_txt2img_api.json

2. Attach in <ComfyuiGW>/workflows_config.json root object:

    "flux_lora_txt2img_api": {
        "prompt_workflow": "workflows/flux_lora_txt2img_api.json",

        }
    },

3. Attach in <ComfyuiGW>/mode_config.json root array (and update the LORA filename):

Tips:

• You can switch the LORA at runtimes, e.g. put <lora:Flux\realisticPhoto_v3.safetensors> at the end of the prompt will replace UltraRealPhoto with realisticPhoto_v3 LORA.
• For easier putting the tag in prompt, you may put <lora:Flux\realisticPhoto_v3.safetensors> in menu -> Prompt -> Auto-complete Phrases
• You may also override the denoise factor at runtime, which maybe useful for inpainting, e.g. putting <denoise:0.5> in prompt.
