AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Purpose
【FLUX】MEGAPACK — v2.0 is for generating and editing images in ComfyUI: it takes text or existing images and outputs generated or edited images through TXT to IMG, IMG to IMG, INPAINT, OUTPAINT, KONTEXT, ControlNet, Upscaler, and LoRA tester workflows.
Inputs and outputs
Use text with TXT to IMG or an existing image with IMG to IMG; the collection also includes INPAINT, OUTPAINT, KONTEXT, ControlNet, Upscaler, and LoRA tester workflows.
Setup
Copy the workflow folder to ComfyUI\user\default\workflows.
In ComfyUI, enable "Use Nodes V2 (Vue)" in Settings, refresh the page, and then load the workflow.
Dependencies
Install the required custom node, ComfyUI-UmeAiRT-Toolkit, through ComfyUI Manager by searching for "UmeAiRT", or use the UmeAiRT Auto-Installer.
ComfyUI-UmeAiRT-Toolkit packages the upscaler, face detailer, and metadata saver; the description says no other custom nodes are needed.
Listed files include flux1-dev-fp8.safetensors or flux1-dev-fp16.safetensors; flux1-fill-dev-fp8.safetensors or flux1-fill-dev-fp16.safetensors; flux1-kontext-dev-fp8-e4m3fn.safetensors; clip_l.safetensors; Model Q8, Q6, Q5, Q4, Q3; FILL Model Q8, Q6, Q5, Q4, Q3; KONTEXT Model G8
Configuration
Place manual Model, FILL Model, and KONTEXT Model files in ComfyUI\models\diffusion_models; place CLIP in ComfyUI\models\clip. For GGUF, place Model, FILL Model, and KONTEXT Model files in ComfyUI\models\unet and CLIP files in ComfyUI\models\clip; place ae.safetensors in ComfyUI\
The listing identifies Flux.1 D as the base model and v2.0 as the version.
Cautions
Without "Use Nodes V2 (Vue)" enabled, the workflow may have display problems.
Before downloading, verify that the page identifies 【FLUX】MEGAPACK — v2.0 by UmeAiRT.
