ComfyUI + Blender = The Ultimate FREE Local 3D Environment Pipeline (Terrain, PBR, HDRI)

In this video, I show how to merge ComfyUI and Blender into one practical, fully local pipeline for building 3D environments from a single image reference. You’ll learn how to install my ComfyUI 360 HDRI Suite (custom nodes + ready workflows), generate seamless textures, extract PBR material maps (albedo, normal, roughness, depth, etc.), create heightfield terrain from a photo, and send the results directly into Blender with live preview. I also cover how to use Ollama for local vision analysis (to generate better prompts from your reference images), and how to generate a proper 360 sky dome / HDRI-style atmosphere that matches lighting direction, intensity, and color so your Blender scene looks consistent and realistic. Everything runs on your own computer, and the workflows are designed to be practical even on mid-range GPUs (with tips on resolution and VRAM limits). If you want a free, offline-friendly workflow for terrain, textures, materials, and lighting—this is the full step-by-step setup and a set of real examples you can reuse in your own projects.
