That’s the power Flux Tools bring to ComfyUI. In this comprehensive guide, you’ll learn everything you need to install, configure, and master Flux Fill, Flux Depth, Flux Canny, and Flux Redux. Whether you’re a digital artist, an AI enthusiast, or a business innovator, these tools will expand your creative possibilities and automate complex workflows. By the end, you’ll not only understand how to use each tool but also how to troubleshoot, optimize, and push the boundaries of AI-powered image generation.

What are Flux Tools? A New Era for ComfyUI

Flux Tools are a suite of advanced AI models created by Black Forest Labs to supercharge ComfyUI’s image generation capabilities. Each tool is designed for a specific workflow:

• Flux Fill: Effortless inpainting and outpainting,fill or extend images with stunning realism.
• Flux Depth: Guide image generation with depth maps for 3D-aware compositions.
• Flux Canny: Generate images guided by edge maps (Canny maps) for sharp outlines and structure.
• Flux Redux: Create variations and blend multiple images, unlocking new conceptual possibilities.

Why Learn Flux Tools?

AI image generation is moving beyond simple prompting. With Flux Tools, you can:

• Repair or reimagine photos with professional inpainting and outpainting.
• Control the structure of outputs with depth or edge guidance.
• Blend visual ideas and styles with unprecedented ease.
• Access and share complex workflows via drag-and-drop images.
• Leverage community resources to troubleshoot and iterate faster.

Getting Started: Installation Requirements and Setup

Before you can use Flux Tools, you need a solid foundation. Here’s how to get started:

1. Update ComfyUI
Always start by updating ComfyUI to the latest version. This ensures compatibility with new nodes and models. Open ComfyUI, use the built-in manager, and check for updates.

2. Download the Flux Models
You’ll need to download several Flux models from the official sources (often via Hugging Face or the Black Forest Labs repositories). The main models include:

• Flux Fill: For inpainting and outpainting (UNET model)
• Flux Depth: For depth-guided generation
• Flux Canny: For edge-guided generation
• Flux Redux: For variation and blending (requires multiple supporting models)
• Laura versions: Smaller, hardware-friendly variants for Depth and Canny

3. Model Placement in ComfyUI
Flux models must be placed in specific folders within your ComfyUI directory for the system to recognize them. Here’s how to organize them:

• UNET models: Place in models/unet
• CLIP models (text encoders): Place in models/clip
• Style models: Place in models/style
• CLIP Vision models: Place in models/clip_vision
• Diffusion models (including Canny and Depth): Place in models/diffusion_models
• Laura models: Place in models/loras

4. Hardware Considerations
Flux models are large. The full versions of Flux Fill, Canny, and Depth can take up significant hard drive space and require substantial GPU VRAM. If you’re limited by hardware, consider the Laura versions (especially for Canny and Depth),these are about 20 times smaller and more manageable.

Example 1: If you have a high-end GPU (e.g., 24GB VRAM), you can use full-size models for maximum fidelity.
Example 2: If you’re on a mid-range card (e.g., 8GB VRAM), try the Laura versions to avoid crashes or slowdowns.

5. Accessing Workflows
One of the most user-friendly features: pre-built workflows are embedded in example images shared on the ComfyUI blog or the pixaroma Discord. Simply drag an image into ComfyUI, and it will load the workflow nodes automatically,ready for you to test and tweak.

Flux Fill: Inpainting and Outpainting

Flux Fill is your go-to tool for repairing, modifying, or extending images by painting in new content. It’s designed for both inpainting (filling missing areas) and outpainting (expanding the canvas with new content).

Inpainting with Flux Fill

Concept: Inpainting is the process of selecting a portion of an image with a mask and generating new, contextually appropriate content within that area.

Workflow Overview:

1. Load your image.
2. Open the Mask Editor. Use the brush tool to paint over the area you want to replace or repair. Tip: Paint the mask slightly larger than needed for a softer transition at the edges.
3. Save the mask. This mask defines the target region for inpainting.
4. Prepare your prompt. Describe what you want the AI to generate in the masked area (e.g., “add a red flower bouquet”).
5. Workflow Nodes:
   • Load Diffusion Model: Loads the Flux Fill UNET model.
   • Dual Clip Loader: Loads CLIP L and T5 for text-prompt conditioning.
   • Differential Diffusion Node: Applies advanced denoising, improving realism.
   • Inpaint Model Conditioning: Combines prompt, latent space, pixel data, and mask to focus generation on the selected area.
6. Run the workflow. Inspect the output and iterate as needed.

Example 1: You have a portrait photo with an unwanted person in the background. Use the mask editor to paint over the person, prompt “replace with lush green foliage,” and Flux Fill will blend new background elements seamlessly.
Example 2: Imagine a product shot missing a logo. Mask the blank area, prompt “add a modern blue logo,” and Flux Fill generates a natural-looking addition that matches lighting and style.

Best Practice: Avoid sharp mask edges. Always paint slightly outside the problem area for a seamless blend.

Outpainting with Flux Fill

Concept: Outpainting extends the canvas of an image, generating new, coherent content in the newly added areas.

Workflow Modifications:

• Replace the inpainting mask with a mask from the Pad Image for Outpainting node.
• Specify the direction and number of pixels to expand (e.g., 200px to the right).
• Adjust “Feathering” to control how smoothly the new content blends with the original.

Example 1: You have a landscape photo with a beautiful sunset cropped too tightly. Use outpainting to extend the sky, prompting “continue sunset with gentle clouds.”
Example 2: Take a portrait and use outpainting to add space above the head for magazine cover text,prompt “expand background with soft bokeh.”

Best Practice: Experiment with prompts and feathering settings to control how much the new content matches or diverges from the original.

How the Nodes Work Together (Inpainting & Outpainting)

• Load Diffusion Model brings in the UNET (Flux Fill) for core generation.
• Dual Clip Loader ensures the AI “understands” your prompt.
• Differential Diffusion enhances the quality of the fill, especially around mask transitions.
• Inpaint Model Conditioning is essential,it fuses your prompt, the mask, and image data so the AI knows what to change and what to keep.

Tip: Save your workflow as a preset. You can reuse your setup for similar projects, saving time and increasing consistency.

Flux Redux: Image Variation and Blending

Flux Redux is designed for creative reinterpretation,making variations of a single image or blending multiple images for unexpected, powerful results.

Image Variation with Flux Redux

Concept: Generate a new image that closely interprets or reimagines an existing image, without being limited to the exact composition or aspect ratio.

Workflow Overview:

• Requires several models:
  • Flux Dev Q8 (core variation model)
  • Q8 T5 Clip model (text conditioning)
  • Style model (influences overall look)
  • Clip Vision patch model (encodes image features)
• Upload your base image.
• Run the workflow. The output is a “faithful interpretation” of the original image, but not a pixel-perfect copy.

Example 1: Upload a hand-drawn cartoon and generate a polished digital illustration,Flux Redux “interprets” the sketch with artistic freedom.
Example 2: Provide a product photo and create variations with different color schemes or lighting,great for marketing or A/B testing.

Tip: Unlike ControlNet, you aren’t locked into the original image’s aspect ratio. Try wide or square variations for creative flexibility.

Blending Multiple Images with Flux Redux

Concept: Combine two or more images to generate a new composition that merges elements from each, often resulting in creative or surreal outputs.

Workflow Steps:

1. Upload the images you want to blend.
2. Chain multiple Apply Style Model nodes,each one introduces a new image’s style and features.
3. Run the workflow. The result is a random combination of visual features from your inputs.

Example 1: Blend a portrait photo with a fantasy landscape illustration,the result might be a stylized character emerging from a magical background.
Example 2: Combine a technical diagram with a watercolor painting,yielding abstract, concept-driven visualizations.

Best Practice: Results are intentionally unpredictable. For more abstract blends, add more images; for a focused mix, use just two. Experiment with the order of Apply Style nodes, as it can influence which image dominates.

Limitations: You don’t have direct control over where elements appear or how they’re combined. Blends can be “strange” or highly abstract, but this is often where new ideas are born.

Flux Depth: Depth-Guided Image Generation

Flux Depth brings a 3D-aware approach to image creation. Guide the AI by providing a depth map,a grayscale image where white is close and black is far,so new images respect spatial structure.

Workflow Overview:

1. Load your source image.
2. Generate a depth map using a pre-processor node (such as Depth Anything pre-processor or ComfyUI’s built-in node).
3. Feed the depth map to the Instruct Pix2Pix Conditioning node.
4. Connect the Flux Depth model directly to the K Sampler (the node that runs the generative steps).
5. Set a high “flux guidance” value (start at 30) to ensure the depth map strongly influences the result and prevents artifacts.
6. Adjust image resolution. Tip: The maximum supported by Flux is 2 megapixels,reduce width or height for wide-ratio images if needed.
7. Run the workflow. Tweak steps, samplers, schedulers, and guidance to refine results.

Example 1: Take a photo of a person and use the depth map to generate a stylized portrait that maintains strong 3D structure.
Example 2: Use a depth map from a landscape photo to guide the generation of a fantasy environment with realistic sense of space.

Best Practice: If results look distorted or have artifacts, raise the flux guidance or experiment with different samplers and steps.

Flux Canny: Canny Edge-Guided Generation

With Flux Canny, edge detection shapes the result. A Canny map captures the outlines and sharp transitions in an image, providing a strong structural guide for the AI.

Workflow Overview:

1. Load your base image (sketch, render, or photo).
2. Generate a Canny edge map using a pre-processor node (ComfyUI’s built-in or external).
3. Send the Canny map to the Instruct Pix2Pix Conditioning node.
4. Connect the Flux Canny model to the K Sampler.
5. Set parameters as you would in Flux Depth. Tip: Start with default guidance, then tweak for desired effect.
6. Run the workflow and observe how the edges are interpreted in the output.

Example 1: Use a simple line drawing of a character and generate a fully colored cartoon, with the AI following your original outlines.
Example 2: Take a 3D render with well-defined shapes, apply a Canny map, and generate a stylized poster or game asset.

Best Practice: Canny works especially well for clear, graphic images. For more organic or photographic sources, experiment with edge map thresholds to avoid “over-structuring” the result.

Laura Versions: Efficient Alternatives for Canny and Depth

Laura (Low-Rank Adaptation) models are lightweight versions of the full Flux Canny and Depth models. They’re ideal for users with limited hardware resources or those seeking faster iteration cycles.

How to Use:

• Load a Laura model using the Power Laura Loader node.
• Adjust the “strength” parameter to control how much influence the Laura model has over the result.
• Integrate Laura into the same workflow as the full model, swapping the main model node for the Laura loader.

Example 1: On a laptop with limited GPU, use Laura Canny for edge-guided generation. Reduce strength for subtle influence; increase for bold, edge-driven results.
Example 2: For rapid prototyping, use Laura Depth to test ideas before committing to high-resolution, full-model runs.

Best Practice: The ability to control model strength is unique to Laura. Start at a moderate value, then dial up or down to balance creativity and fidelity.

Comparing Full Models and Laura Versions

• Full Models: Higher fidelity, require more storage and VRAM, placed in models/diffusion_models.
• Laura Versions: Dramatically smaller, placed in models/loras, strength control via Power Laura Loader.

Workflow Accessibility: Drag-and-Drop and Community Sharing

One of the most empowering aspects of Flux Tools is workflow accessibility. You don’t need to build complex node trees from scratch,just drag an example image into ComfyUI, and it loads the entire workflow instantly.

How it works:

• Visit the ComfyUI blog or the pixaroma Discord to find example images.
• Download and drag an image into your ComfyUI window.
• The embedded workflow loads automatically, including all necessary nodes and settings.
• Swap in your own images or prompts to begin experimenting.

Example 1: Download an inpainting workflow image,drag it into ComfyUI, and you’re ready to mask and prompt in seconds.
Example 2: Use a shared blending workflow from Discord; replace images with your own to create unique combinations.

Best Practice: Save your favorite workflows as presets, and share your own examples with the community.

Frequently Asked Questions

This FAQ provides practical answers to the most common and important questions about installing and using Flux Tools,including Flux Fill, Redux, Depth, and Canny,within ComfyUI. Whether you’re just starting or looking to refine your workflow, the following sections will walk you through setup, troubleshooting, workflow design, model management, and advanced creative strategies, all with business-focused clarity.

What are Flux Tools in ComfyUI?

Flux Tools are a suite of models from Black Forest Labs that expand ComfyUI’s image generation and editing capabilities.
They include Flux Fill (for inpainting), Flux Depth (for depth-map-guided generation), Flux Canny (edge map guidance), and Flux Redux (image variation and combination). Each tool offers a unique way to guide, modify, or enhance images, unlocking a broader range of creative and professional use cases.

How do I install Flux Tools and models in ComfyUI?

Installation starts by updating ComfyUI and all nodes using the manager’s “update all” option.
After restarting ComfyUI, download the Flux models you want from sources like Hugging Face. Each model type (UNET, Clip, Style, Laura, Diffusion) goes into a specific subfolder in your ComfyUI/models directory (e.g., models/unet, models/clip, models/loras, models/diffusion_models). Some downloads require agreeing to terms. Follow video or written instructions closely to ensure correct placement.

What is Flux Fill and how is it used for inpainting and outpainting?

Flux Fill streamlines inpainting by letting you mask out image sections and generate new content for those regions based on your prompt.
Load your image, use the mask editor to select what to change, then describe the target content. The workflow fills the masked area and blends it into the original. For outpainting (expanding the canvas), add the “pad image for outpainting” node and adjust the mask source, allowing the model to generate content beyond the image’s original borders.

How does Flux Redux work and what are its capabilities?

Flux Redux creates variations of an input image, functioning as a style transfer or hybridizer rather than a pure composition replicator.
Use the “apply style model” node, provide a style and vision model, and optionally combine multiple images for novel outputs. Results can be familiar or abstract, depending on input diversity. Unlike ControlNet, Redux doesn’t lock in composition and can output different aspect ratios or combine image features in unpredictable ways.

What is the role of Flux Depth and Flux Canny in image generation?

Flux Depth uses depth maps and Flux Canny uses edge maps to guide image generation toward specific compositional structures.
Each requires appropriate models in the diffusion_models folder and pre-processing nodes (depth map or Canny edge map generation). These tools work much like ControlNet, conditioning the AI model to honor spatial or structural cues from the input image.

Are there smaller versions of Flux Canny and Flux Depth available?

Yes, Laura (Low-Rank Adaptation) versions exist for both Flux Canny and Flux Depth.
These lighter models go in the loras folder and work with a “power Laura loader” node, letting you fine-tune their influence on the final image. This is ideal if you’re short on storage or want more nuanced control over model effects.

Where can I find workflow examples and get help with Flux Tools in ComfyUI?

Workflow examples are available on the ComfyUI blog and often embedded within sample images.
You can drag these images directly into ComfyUI to load the workflow. For further help, join the Pixaroma Discord server, which has dedicated channels and FAQs for ComfyUI, including Flux Tools. These resources offer troubleshooting tips, community support, and workflow sharing.

What are some important considerations when using Flux models, especially regarding hardware and settings?

Full Flux models are large and require ample storage and VRAM.
Check your hardware before installing, especially for high-resolution or wide-aspect image generation. Mind the 2-megapixel size limit for some workflows. Experiment with steps, samplers, schedulers, and guidance values to tweak results and avoid artifacts, especially when pushing model limits or working with unusual aspect ratios.

What is the primary function of Flux Fill in ComfyUI, and how is it typically used?

Flux Fill’s main purpose is inpainting,replacing masked parts of an image with new, prompt-driven content.
You select an area to alter, describe the desired change, and the model generates a result that blends with the original. This is widely used in product photo editing, creative marketing, and restoring or updating visuals without retaking photos.

How does the Flux Depth model work to influence image generation, and what kind of input image does it require?

Flux Depth uses a depth map,an image representing distance information,as a guide for generating new images.
A pre-processor converts your source image into a depth map, which is then used to influence the AI’s understanding of spatial relationships in the scene. This is useful for architectural renderings, product visualizations, or any scenario where realistic spatial consistency matters.

What is the purpose of the differential diffusion node in the Flux Fill workflow?

The differential diffusion node enhances denoising by applying a mask-aware function during image refinement.
It ensures the AI focuses on changing only the masked area, preserving nearby details and blending more smoothly. This results in sharper, more natural edits,especially critical for business use cases like product photography where seamlessness is key.

What is the key difference between using the full Flux Canny model and the Flux Canny Laura model in terms of control?

The Laura version allows you to adjust its influence using a “power” slider, while the full model does not offer direct strength control.
This flexibility is useful for fine-tuning results, especially if you want the effect to be subtle rather than dominant. In contrast, the full model always applies its guidance at a fixed strength.

How is the Inpaint Model Conditioning node essential for the Flux Fill workflow?

This node prepares and combines all necessary inputs,prompt, latent image, pixel data, and mask,for the inpainting process.
It ensures the diffusion model knows exactly which area to alter and how to blend new content with the existing context. Without it, inpainting wouldn’t focus properly on the selected region.

Describe the functionality of the Pad Image for Outpainting node and how it modifies the workflow.

Pad Image for Outpainting extends the image canvas and generates a mask for the new area.
This transforms a standard inpainting workflow into an outpainting process, allowing you to grow your image in any direction and fill the expansion based on your prompt. It’s ideal for creating banners, adding context to product shots, or adapting images for new formats.

What is the core concept behind the Flux Redux model and how does it differ from ControlNet or standard image-to-image generation?

Flux Redux focuses on generating variations that are similar to the input image without strictly preserving composition.
Unlike ControlNet (which tries to keep structure intact) or standard img2img (which can distort aspect ratios), Redux allows for creative reinterpretation,even across different dimensions. It’s especially useful for style transfer, abstract brand visuals, or rapid prototyping of ideas.

When combining multiple images using the Flux Redux workflow, what kind of results are generally expected?

The output is usually a blend of features from each input image, often resulting in abstract or surprising combinations.
This unpredictability can be a creative asset for brainstorming, visual ideation, or developing new marketing concepts. The more images provided, the less literal and more creative the result.

What pre-processor node is required when using the Flux Depth model to generate a depth map?

The “Depth Anything” pre-processor node is commonly used to create a depth map from a source image.
This depth map becomes the guide for Flux Depth, ensuring the generated image respects the original’s spatial structure.

Where are the Flux Canny and Flux Depth full models typically installed within the ComfyUI folder structure?

Place them in the models/diffusion_models directory under your ComfyUI installation.
This allows ComfyUI to recognize and load them for use in relevant workflows, ensuring seamless integration.

How do I update existing Flux models in ComfyUI?

Use ComfyUI’s manager to update nodes and occasionally check model sources like Hugging Face for new releases.
Replace old model files with newer versions in the correct folders and restart ComfyUI. Always back up your workflows before updating in case of compatibility changes.

Can Flux Tools be used on business product photos?

Absolutely,Flux Fill is ideal for removing unwanted objects or updating details in product shots, while Flux Redux can generate styled variations for marketing.
Use Flux Depth or Canny for consistent visual themes or to adapt assets for new campaigns, saving time on reshoots and manual editing.

What are common errors or challenges when installing Flux models?

Misplacing model files, failing to update ComfyUI, or missing dependencies are typical issues.
Double-check folder paths, ensure you’ve agreed to any required terms on model hosting sites, and confirm hardware compatibility. If models don’t appear, verify file extensions and locations.

Is it possible to control the strength of influence for Flux Depth and Canny models?

Yes, for Laura versions,use the “power Laura loader” node to adjust influence. The full models do not support direct strength adjustment.
This control is useful for subtle edits or when mixing multiple guidance sources.

Can I use Flux Tools with low VRAM hardware?

You can use the smaller Laura models for Flux Depth and Canny if you have limited VRAM.
These models require less memory and processing power, making them accessible for users with modest hardware. For large-scale or high-res tasks, more powerful GPUs are recommended.

How do I convert an inpainting workflow to outpainting in ComfyUI with Flux Fill?

Add the “pad image for outpainting” node and connect it as the mask source instead of the mask editor.
This node expands your canvas and masks the new area, allowing the workflow to generate content beyond the original image’s boundaries.

What business use cases benefit most from Flux Redux?

Brand identity design, creative brainstorming, and campaign prototyping all benefit from Flux Redux’s ability to generate unique image variations from existing assets.
You can quickly explore new looks, merge influences, or derive abstract visuals for branding or advertising.

How do I troubleshoot artifacts or unexpected results in Flux workflows?

Adjust steps, samplers, schedulers, or guidance strength, and check your mask or map quality.
Artifacts often arise from overly aggressive settings or low-quality masks. Try smaller increments, refine your mask, or use higher-resolution source images.

What types of model files are needed for a complete Flux Fill setup?

You’ll need the UNET model, at least one Clip model, and sometimes a style or Laura model, placed in their respective subfolders.
Refer to the installation guide for precise file locations. Missing any required model will prevent the workflow from functioning.

Can I use Flux Tools to edit images with people or complex scenes?

Yes,Flux Fill and Redux handle complex scenes and human imagery well, provided the mask and prompt are accurate.
Flux Depth is particularly effective for scenes where spatial accuracy matters, such as group photos or event images.

How do Flux Fill, Flux Depth, and Flux Canny differ in guiding image generation?

Flux Fill uses a mask for targeted edits, Flux Depth uses a depth map for spatial guidance, and Flux Canny uses edge maps for structural control.
Each addresses a different aspect of image transformation,content, space, or edges,allowing precise tailoring for specific creative or business goals.

Do I need to use a prompt with Flux Redux?

No prompt is required, but providing one can help guide the visual theme or style of the output.
If you want more control over the result, use a prompt; for pure variation or abstract results, omit it.

What is the best way to learn Flux workflows for team use?

Start with sample workflows from the ComfyUI blog or community Discord, experiment with edits, and document your process for your team.
Share workflow files, encourage team members to try variations, and build a library of best practices tailored to your business needs.

Can Flux Tools be automated or batched for large projects?

Yes,ComfyUI supports batch processing and scripted workflows, allowing you to process multiple images using the same Flux Tool setup.
This is useful for large-scale content adaptation, e-commerce catalog updates, or marketing material generation.

How do I decide between using the full model or the Laura version of Flux Depth or Canny?

Choose the full model for maximum quality and the Laura version for smaller file size and adjustable influence.
If you need to fine-tune the effect or have hardware/storage constraints, Laura versions are usually preferable.

What is the role of the Clip Vision model in Flux Redux workflows?

The Clip Vision model encodes visual features of the input image(s), which are then referenced by the style model during generation.
This helps preserve certain aspects of the source while allowing creative reinterpretation, making it valuable for consistent branding or creative remixing.

Are there any licensing or usage restrictions for Flux models?

Some models require agreement to specific terms before downloading, especially for commercial use.
Always review the licensing on platforms like Hugging Face or the developer’s documentation to ensure compliance.

Can Flux Canny or Depth be used with other ControlNet-like models?

Yes, but results may be unpredictable, and not all combinations are supported by default.
Experiment cautiously, and pay attention to workflow documentation to avoid conflicts or degraded output quality.

What should I do if Flux models don’t show up in ComfyUI?

Check that models are in the correct folders, have the correct file extensions, and that ComfyUI has been restarted after installation.
If the problem persists, review the log output for missing dependencies or compatibility errors and consult community forums for troubleshooting.

How can I share my custom Flux workflows with colleagues?

Export workflow files directly from ComfyUI and share them via your internal platform or the ComfyUI Discord.
Attach relevant model files or specify required models to ensure reproducibility on other systems.

Are there best practices for prompt writing in Flux Fill or Redux?

Use clear, descriptive language that matches your business context and desired outcome.
For consistent results, standardize prompt templates for common tasks (e.g., “add a white background for e-commerce” or “change product color to blue”).

How do I handle large or wide-aspect images with Flux Depth?

Be mindful of the 2-megapixel size limit. Resize images or split them into sections if necessary.
This prevents memory errors and ensures reliable processing, especially on standard GPUs.

Can I use Flux Tools for non-photographic art or illustrations?

Yes,Flux Tools are effective for creative, non-photo applications like digital art, concept sketches, or illustrated marketing assets.
Experiment with masks, depth, or edge maps to create stylized or abstract results tailored to your project’s needs.

How do Flux Tools fit into a business content production workflow?
