Learn to build a complete local 3D environment creation pipeline by integrating ComfyUI with Blender for terrain generation, PBR material extraction, and HDRI lighting from single reference images. Install the custom ComfyUI 360 HDRI Suite node pack and workflows, then set up the connection between ComfyUI and Blender using the provided addon system. Generate seamless textures with proper tiling preview, extract physically-based rendering maps including albedo, normal, roughness, and depth channels using the Ubisoft PBR Extractor model. Create realistic heightfield terrain from photographs using vision analysis through Ollama's local AI models for enhanced prompt generation. Master the workflow for generating 360-degree sky domes and HDRI environments that match your reference image's lighting direction, intensity, and color temperature. Configure live preview functionality to send generated terrains, materials, and 3D models directly into Blender for real-time iteration and refinement. Optimize the pipeline for mid-range GPUs with practical tips on resolution limits and VRAM management, ensuring the entire workflow runs offline on your local machine without external dependencies.
