Flux.2 Klein Mix Workflow

Workflow with main focus on Image Editing, with control over Image Sizes. Trying to only use the more common Custom Nodes or ones that do not have requirements for a easy and safe installation.
Aiming for consistency and support edits for up to 4 images and Text to Image, 3 different Controlnets, different Inpainting methods and Outpainting. Nodes for selecting image sizes and Aspect Ratio. Uses Flux2 Klein Enhancer nodes, for consistency and prompt impact. Color matching and different sampler with ETA setting.
The workflow has many notes that explain things inside, which you can read or delete.

There is a second Version inside for people that use Lora Manager so you can pick what you want.

The workflow only support a Positive Prompt except for the 2-pass mode in V5 for T2I that uses both the Base and the Normal model and a negative prompt.

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
CRZnodes
mxToolkit
ZImageTurbo-FlowSampler



Note that V2 and V1 do not use the same custom nodes, and are harder to use because of that, and I do not recommend using them!
