Using Opus 5.5 to model, rig and animate 3D scenes in Blender
The author shares a workflow where Opus 5.5, through the Blender MCP server, orchestrates Blender Kit assets to build 3D scenes, rig characters and render animations.
claude opus 5.5 can now build, rig and animate full 3d scenes inside blender... the trick is letting opus orchestrate instead of model, but there’s a smart way to set it up: - step 1: install blender 5.2.2 and the official blender mcp server - step 2: open claude, pick opus 5.5 on high effort, run /mcp to confirm blender is connected - step 3: install blender kit (edit > preferences > install from disk) for 140k+ free models, materials and hdris - step 4: ask opus “can you see the blender kit library?” so it runs a test search before you build - step 5: paste a reference image and a plain prompt. talk to it like a junior 3d designer, no structured prompts - step 6: for characters, ask for the rig in the same prompt (“keep it realistic, rig it for smooth animation”) - step 7: render a 480p preview first, then the final render (1080p can take 1-2 hours) who does what: - blender kit: chairs, couches, cars, wood beams, textures - opus 5.5: writes the code, places assets, sets lights, rigs, animates - blender: renders every frame - you: review and fix the small stuff by hand and the rule that saves the project... never let opus build a chair from scratch. it burns tokens and still looks fake. pull the asset and let opus arrange it i like to check animations step by step before the final render. a glitch you miss early costs you 2 hours later
