⚙️ How It Works

This LoRA leverages the FLUX.1 Kontext architecture - a 12B parameter rectified flow transformer trained in latent space with fused DiT blocks and 3D Rotary Positional Embeddings (RoPE). The model has been fine-tuned on a curated dataset of floor plan-to-color render pairs to learn the mapping between 2D CAD layouts and architectural color representations.

🔬 Core Mechanism

graph LR
    A[📄 2D Floor Plan<br/>CAD/Blueprint] --> B[🧠 FLUX.1 Kontext<br/>12B Transformer]
    B --> C[⚡ LoRA Injection<br/>Low-Rank Weights]
    C --> D[🎯 Spatial Understanding<br/>RoPE Encoding]
    D --> E[🎨 Style Transfer<br/>B&W / Pure Color / Color Scheme]
    E --> F[🏠 Color<br/>Visualization]
  1. 📄 Input Conditioning - The model accepts a 2D floor plan image (CAD drawing, architectural sketch, or blueprint) as the primary input.

  2. ⚡ LoRA Injection - The fine-tuned low-rank weight matrices are injected into the base FLUX.1 Kontext transformer, specializing the model's attention heads to recognize architectural elements (walls, doors, windows, furniture, spatial layouts).

  3. 🎯 Spatial Understanding - Using FLUX.1 Kontext's advanced in-context generation capabilities and RoPE positional encoding, the model interprets the 2D layout as a spatial structure.

  4. 🎨 Style Transfer - The LoRA applies learned aesthetic patterns to generate three distinct visual styles: Black & White, Pure Color, and Color Scheme.

⚠️ Limitations

  • Resolution Cap: Hard limit at 1024x1024 px; intricate geometry may produce edge artifacts at lower resolutions
  • Multi-View Consistency: No built-in guarantee for fully coherent scenes across multiple angles
  • Complex Geometry: Highly detailed or irregular architectural elements may require manual refinement
  • Style Lock: The model is optimized for the three trained styles; deviations may produce inconsistent results
