Important: All versions of V1, V2 and V3 can be downloaded by clicking the buttons on the right. From top to bottom are V3, V2, V1. If your project requires relighting capabilities, please use Flux Background Replacer V2, as Flux Background Replacer V3 does not include this feature. Below is a detailed comparison to help you understand the key differences between the two workflows: Key Differences Between ‘Flux Background Replacer V2’ and ‘Flux Background Replacer V3’: Node Count and Complexity: Flux Background Replacer V2: A highly complex workflow featuring over 108 nodes, ideal for scenarios where precise image manipulation and blending are essential. Flux Background Replacer V3: With a more streamlined design, V3 contains 80 nodes, providing a simpler and more efficient workflow without compromising on quality. ControlNet Model and Edge Handling: Flux Background Replacer V2: Utilizes the ControlNet Canny model from Xlabs, which is specifically designed for advanced edge detection and outline preservation. This, combined with its relighting function, allows for photorealistic integration of subjects into the new background. Flux Background Replacer V3: Uses the ControlNet Depth model and Upscaler model from Jasper AI, optimized to control edges and outlines without the need for additional specialized nodes. This makes it easy to use the ‘Apply ControlNet’ node, saving time and simplifying setup.

Flux Kontext Fast + Upscale Workflow Status: Work in Progress - Still refining output quality This workflow combines the power of FLUX.1 Kontext with the Alimama Turbo LoRA to achieve fast, high-quality image generation and upscaling in just 8 steps. Key Features Fast Generation: Utilizes the alimama-creative/FLUX.1-Turbo-Alpha LoRA for rapid image generation with only 8 inference steps Context-Aware Editing: Leverages FLUX.1 Kontext capabilities for intelligent image editing and manipulation Two-Stage Process: Initial generation followed by upscaling for enhanced detail and resolution Efficient Workflow: Optimized for speed while maintaining quality output Workflow Components Stage 1: Fast Generation Model: FLUX.1 Kontext with Turbo Alpha LoRA Steps: 8 (significantly reduced from standard 20-50 steps) Guidance Scale: 2.5 (optimized for Turbo LoRA) Sampler: Euler with simple scheduler Stage 2: Upscaling Method: Ultimate SD Upscale with custom sampling Upscale Model: 4x-ClearRealityV1 Tile Processing: Intelligent slicing for memory efficiency Denoising: 0.2 strength for detail enhancement Technical Setup Required Models FLUX.1 Kontext DEV (FP8 quantized) Alimama FLUX.1-Turbo-Alpha LoRA 4x upscale model Standard FLUX text encoders (CLIP-L + T5) Memory Optimization FP8 model quantization for reduced VRAM usage Tile-based upscaling to handle large images Optional caching nodes for faster iterations Prompt Guidelines The workflow works best with detailed, descriptive prompts. The Turbo LoRA has been trained on high-aesthetic images (6.3+ rating) with resolution >800px, so it excels at: Detailed scene descriptions Lighting and atmosphere specifications Style and aesthetic directions Object replacement and background changes Current Limitations ⚠️ Work in Progress: Output quality is still being refined Some inconsistencies in fine details Occasional artifacts in upscaled regions This workflow represents an efficient approach to context-aware image editing with FLUX, trading some quality for significant speed improvements. Perfect for rapid prototyping and iterative design work.
